The show off ape

An ape lives in the jungle with all his mates. He’s a special ape, a bit of a show off,
always swinging through the trees performing stunts and acrobatics. All is well until one
day he has a serious fall. He lands badly breaks both his knees. Well his mates are
gutted, and so they rally around and carry him to a doctor.
The doctor examines him and says, “Sorry pal your acrobatic days are over. Unless,
unless we can get two replacement knee caps.” Well kneecaps replacements are hard to
find in the jungle, so the animals have a whip round. They raise the princely sum of 1
penny. They give the money to a tiger and send him to the nearest medical supply centre.
The tiger treks for days with the money, but eventually finds the centre. When he gets
to the front of the queue he pulls out the cash and says, “Do you have two ape knees for
a penny?”
