Most good jokes I know are long ones, but this is one of the least long ones.
An Indian chief had a big fart on its way, but it wouldn`t come out. So he called for his messenger boy and told him: "Go to our medicine man and tell him "Big chief, no fart".
And the boy ran off and told the medicine man those exact words. "Oh, I see. Here`s a can of baked beans, that`ll help". The boy ran off but came back after a while and said the same thing: "Big chief, no fart".
"Right. Well, here are ten cans of baked beans. It should come out now". The boy went but came back after some time with the exact same message. The medicine man got slightly annoyed. "OK, here`s a hundred cans of baked beans. If that doesn`t work, nothing will".
The boy ran off, and after a long time he came back, eyes as big as saucers. "Big fart, no chief".
