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

"Please explain, Tommy," 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 'fuck' the dog ate him!"
