More jokes

A taxi driver in New York City, is nearing the end of his shift. He decides that he will pick up one more person before he calls it a night. He sees someone waving, pulls over and a nun gets into the cab. She tells him where to go and they start off. It's a long drive and the cabbie keeps looking at the nun through the rear view mirror. The nun starts wondering what is going on and says "Um... can I help you, my son?"

The taxi driver looks very embarrassed and says "No I'm sorry... it's very embarrassing, I shouldn't say."

And the nun looks at him and says "Now, my son, I have been in this business far too long to be disturbed by anything you might have to say...so please, go ahead."

The driver thinks for a minute and says "Ok, well for as long as I can remember, I have had the biggest fantasy about kissing a nun."

She looks amused at first then replies, "Well, I think I can help you with that, but first you must promise me two things. The first is that you are a Catholic, the second is that you are single. If you can promise that, then I shall give you what you ask for."

And the driver says "Great! I am a single Catholic!"

So they pull into an alley and the nun crawls into the front seat of the cab and gives the driver an amazing kiss. Porn stars would be envious of this kiss.

They finish up and get back on the road. Soon the taxi driver starts looking nervous and peering at the nun in the rear view mirror again. Just staring at her. The nun asks him "What is it now?"

"Well I'm afraid I haven't been completely honest with you... you see, I'm not a catholic... and I'm also married."

The nun smiles and says "well I haven't been completely honest with you either. My name is Kevin, and I'm on my way to a costume party."
 
I could see that one coming but it's still a good one! It reminds me of an old joke I like:

A white horse goes into a bar. Barman asks what he'd like. The white horse says "oh, I don't know - what's popular? I've never been in a bar before".

The barman says "well beer is popular and then maybe whiskey?"

The white horse says "Oh I've heard of whiskey! I'll have one of those thanks!"

Barman asks "What kind? I have lots of different brands - I have Jack Daniels, Buffalo Trace... and if you want Scotch whisky I have Johnny Walker, Chivas Regal - and I even have one named after you!"

The white horse says "What?? Kevin?"

An amusing answer to "Explain in layman's terms Vgs and Vgs(th) of MOSFET's"

Context:
Vgs is the gate to source voltage. In the datasheet you'll find an absolute term Vgss this is the maximum voltage that can be applied between the gate and the source. Beyond this, you risk damaging the mosfet. An N channel mosfet is essentially a P type sandwiched between two N type regions.

Party Time!
You are hosting a party and inviting all the neighborhood electrons to attend. So you broadcast "PARTY AT MA HOUZE YOLO #SWAG!". I.e. you apply a positive voltage at the gate with respect to the source. Given that your neighbors are some distance away (next door), your broadcast isn't loud enough (You are below Vgs(th)) Once you yell your invite loud enough (i.e. Have Vgs at Vgs(th)) your next door neighbors hear and come party with you.

Vgs(th) is the voltage at which the mosfet channel begins to conduct. At this voltage, a positive voltage, it creates an electric field, which attract electrons (since our applied voltage is positive, so positive charges on gate). These accumulated electrons near the gate, form a bridge between the source and the drain (which are both n type). Now you have a "continuous" n type path from source to drain.

You only attracted your next door neighbors, so your party is kinda lame. How do you get more people? You broadcast louder (Increase the range of your electric field - increase your Vgs).

Now, there's loud, and then there's HOLY CRAP, A PLANE IS ABOUT TO CRASH INTO OUR HOUSE, WHAT THE $#@! IS THAT NOISE!?! We don't want to freak people out too bad, so we need to know how much louder (the difference between) our call is than the minimum needed for just our immediate neighbors (Vgs(th)). This difference is called by a couple of different names, but the two that I've heard most often are V-on (Von) or V-overdrive (Vov). This quantity (Vgs-Vth) represents how much more potential is between the gate and the source than is needed for the transistor to turn on, and it influences just about every other behavior of the MOSFET: current in triode (how many people are at your party when just your neighbors can hear), current in saturation (how many people are there when it's full of people), and transconductance (how much volume you need per person at the party), just to name a few.

So now you've increased your Vgs to the point that you cannot accept anymore people on your property. You are completely full. You can broadcast your party as much as you want, but there simply isn't enough room to accommodate everyone. Your transistor is now in saturation. [Technically, more people can be at the party: if your immediate neighbors start broadcasting the party (increasing Vds), and people start partying at their houses (the source and the drain), this increases the number of people at the party (increased current). This is called channel-length modulation. However, this can only happen if your house is already full (channel-length modulation only happens when the device is in saturation).]

If you start increasing your Vgs to the point of Vgss, well...cops show up and shut you down. Underage drinking, drug use etc.. You go to jail (Your transistor has been damaged).

Which episode? If youtube won't cough it up, I'm sure I can find it elsewhere.

Season 2, Episode 4, titled "A Night Out in London". I figured Youtube would be visible globally for that clip.

Incidentally there's a real life inservice bus in Birmingham UK with a number plate in homage:

This comes from a country noted for its stuffy, aloof people.. when a competition was run for naming a UK ocean exploratory ship, the winning entry was "Boaty McBoatface". The competition judges decided to take the fourth place entry "Sir Richard Attenborough" but in a conciliatory move named the boat's deep sea UAV "Boaty McBoatface" instead (https://en.wikipedia.org/wiki/Boaty_McBoatface).

This morning, the wife was standing in the kitchen, preparing our usual soft-boiled eggs and toast for breakfast, wearing only the T-shirt she wears to bed. As I walked by, half awake, she turned to me and said softly "You've got to make love to me this very moment!"

My eyes lit up and for a second I thought "Am I dreaming , or is this my lucky day?" Not wanting to lose the moment, I embraced her and then gave it my all, right there on the kitchen table.

Afterwards, she said, "Thanks," and returned to the stove, the T-shirt still around her neck.

Happy, but a little bit puzzled, I asked "What was that all about?"

She explained, "The egg timer's broken."
