Little Johnny is sitting in a biology class,and the teacher says that an
interesting phenomenon of nature is that only humans stutter, no other
animal in the world does this.
Johnny's hand shoots up. "Not correct, Miss!" he says.
"Please explain, Johnny," replies the teacher.
"Well, Miss, the other day I was playing with my cat on the verandah. The
neighbours' Great Dane came around the corner, and my cat went
"ffffffffff! ffffffffffff! ffffffffff!", and before he could say "FUCK
OFF!", the dog ate him!"
