Boxing Tigers

How come you never see boxing tigers?
   I saw an old video - used to be 8mm film - of cats boxing. I don't know the context, but it was clearly a pre-PETA thing, where some guy in a dark suit had built a cat-sized boxing ring and then put gloves on two cats. He'd pick them up by scruff of their necks and they'd flail at each other with their boxing gloves until he set them down again.
   It was terrible, and not just because it was cruel, but because it wasn't funny. It was clearly supposed to be funny - cats with boxing gloves, hilarious! - and the guy in the suit certainly had a good time picking up the cats, but it didn't deliver the goods.
   As a matter of fact, back in the 30's, 40's, 50's, when we saw the world in black-and-white newsreels or kinescopes of old TV shows, they'd put boxing gloves on just about any animal. Kangaroos, orangutans, little monkeys, ostriches, otters, I remember seeing all of these at one time or another. Clearly intended to be funny, but not really funny at all.
   Ah... but tigers with boxing gloves, now we're talking something entirely different. Why would this be funny when the others aren't? Because somebody has to go put the gloves on the tiger. See, it's easy to force gloves onto cat's paws, or onto a compliant orangutan's hands, but tigers aren't really down with the sweet science, and they certainly don't like people screwing around with their feet. And, assuming someone actually does get boxing gloves onto a tiger's front paws, chances are good the gloves aren't going to last very long, seeing as how tigers have big ol' claws and fangs.
   I think we should have a reality show where we take people from other reality shows and have them try to put boxing gloves on tigers. I figure we take everybody from Survivor and see just how tough they really are, and the douchebags from Jon and Kate, and all of the Kardashians. I'll bet we'd have some pretty fat tigers after a while.
