What a tease! Great apes pull hair and poke each other for fun

We are great apes and we do that, so…

I love that they've done a study to prove what all zookeepers know. Chimps actually mock each other, like if one chimp has a bad foot and does a limp other chimps will do the limp to take the piss. All the youngsters will pick on older ones that they know can't or won't chase them down.
