Why Did The Turkey Cross The Road?

To prove he wasn't chicken.

One day an Elephant, a Lion and a Chicken were discussing who was 'hardest'.
The elephant said:"When I scream, everybody gets out of my way."
The lion said"That's nothing. When I roar, the whole jungle trembles."
Then the chicken speaks.
"Forget it boys. When I cough, the whole world shits itself."
