I'm being picky, but what chimp with a rock is going to be able to take on a lion? The cats are killing machines, and a chip with a rock wouldn't stand a chance, no matter how big the rock or smart the chimp. "If your pet cat was as big as your dog, you would be lunch", as someone pointed out
Whoops...Never mind...*W*..if u had been u wouldnt be here..
Don't be picky. Substitute "A pointy stick". A chimp could kill a lion with a pointy stick. Men do.
