A cute joke, from MENJ:
A bear, a lion and a chicken meet.
The bear says: "If I roar in the forests of North America, the entire forest is shivering with fear."
The lion says: "And if I roar on the great plains of Africa, the entire savannah is afraid of me."
Says the chicken: "Big deal. I only have to cough and the entire planet $#|+$ itself."
