At an international meeting, two surgeons were having an argument. The Indian surgeon was saying, No no no, I am telling you it is Woomba

The African surgeon is saying, No Man, it is Whoooooommmmmm

They go on like this for about 10 minutes. Up comes the English surgeon, and interrupts them. Excuse me chaps, but I do believe that the word you are trying to say is Womb.

After he has gone away, the African turns to the Indian and says, I bet you he has never even seen a hippopotamus, never mind heard one fart under water!
