I think maybe a medium sized primate would be fair game, not a gorilla or orangutang but definately a large chimp. It would also help if said chimp was wearing a pink leotard as was the custom in the early eighties.
I also reckon i could knock out a large snake as they only have small heads, if you got a good firm punch on the top of the head whilst it was on say a concrete floor i think you could do some serious damage. If were going on weight as an indicator of size this would be a good contender. However if were going on stature and height from the ground then i'm just a regular pussy.
i would like to think that i would be able to knock out one of those ostrich things. whats the conditions here, if you hit them and fail to ko them are they allowed to fight back? are they tied down or something?
id fancy my chances up against a donkey or a horse. im rekoning that theres an area just behind the main jaw bone that could kill it. that part underneath their ears about 6inchs. and i saw mungo do it on blazing saddles. thats the funniest slapstick ive ever seen on a film man. fat guy knocks out a horse. yeah i reckon i could take down a horse.
Not quite sure about the horse or donkey, they are some thick skulled muvva fockers shaamon.
I reckon I could knock out a fox or a badger easy, a duck or a chicken would be a piece of **** aswell. I'm happy to go head to head with an owl to, but I quite fancy a swan. I've heard rumours they can kill a man but i'm not convinced and they all belong to the queen so it would be like beating up a member of the royal family, and you might get beheaded. But I really wanna see what they taste like!
