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 neighbors' Great Dane came around the corner,
and my cat went "ffffffffff! ffffffffffff! ffffffffff!", and before he could
say "F$@%$K OFF!", the dog ate him!"
