As a photographer I have had some weird stuff to shoot for ads, etc. I've had to shoot cows a few times - once for a university and I hopped a fence into a paddock full of cows and was happily snapping away until one cow, bigger than the rest, started trotting straight towards me. As I looked closer I noticed it didn't have the same appearance as the rest of the cows, and didn't even have udders! So I back away and managed to hop back over the fence just as the bull came up to me. Man he was a big fella!
Another time I had to get a close-up shot of a cow's head looking to camera with a wide-angle lens for an ad for pasture fertiliser. Every time I got a cow lined up I would get one shot and the sound of my Hasselblad shutter would scare it off to the far side of the paddock. After a few attempts the art director got the fella who ran the farm and he got the "head cow" to pose for me. So wrapped up in getting the shot was I that I didn't notice that we were drawing a crowd. After getting the last shot I stood up, turned around and there was a neat semi-circle of cows watching everything we were doing - exactly like a Larson cartoon. As I stood up they all pretended to look the other way as if they hadn't really been watching and slowly they all wandered off. It has to be one of the most ridiculous, funniest things I have ever witnessed.
