I would love to have a son like Little Johnny?

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.

Little Johnny's hand shoots up. "Not correct, ma'am!" he says.

"Please explain, Johnny," replies the teacher.

"Well, ma'am, the other day I was playing with my cat on the porch. When the neighbors' Great Dane came around the corner, my cat went 'ffffffffff! ffffffffffff! ffffffffff!' and before he could say '****' the dog ate him!"
