An average American teenager (male, 16 years old) vs. 12 rabid tom cats. No weapons, kid is wearing a t-shirt and gym shorts. Assume an adequate amount of rabies medicine available should the teenager live.
Teenager.
While ole ben ji was no slouch on the athletic field(First team 2A all state in football(2 years) AND wrestling(5 years)) I would have no problem destroying those 12 stupid kitty cats without getting a scratch on me. Assuming I'm in the center circle of a basketball court(pussy sport btw) and the cats come at me equally from all sides....I would easily drop kick the first one and follow through to hit AT LEAST 4 more tom-cats. That leaves 7 left....Lets say 2 jump on my back while I'm drop kicking those 5 tom-cats....well guess what? I've got 2 hands, BOOM 7 DOWN AND 5 LEFT.
Now these 5 that are left have decided to regroup and check for weaknesses(there are none) slowly circling me until I suddenly realize I'm backing in a corner....I'd imagine 2 would lunge for my face while 2 lung for my legs, the general hangs back....As the two TOM-CATS lunge towards my face I do a quick "Shoot(Wrestling term)" and duck the two airborn cats who find their necks snapped as they crash into a concrete wall. While following through with the "Shoot" I grab the 2 leg attacking Tom-Cats with each of my hands before tossing them aside leaving only me and the general who wants nothing to do with me and Runs away like a scaredy cat.
An average American Teenager? Meh, they would get some deep scratch wounds on 3/4 of their body but they would prevail eventually.
