Little Billy at the back of the classroom was waving his arm.
The teacher points to him and says, “Do you know what I’m talking about Billy?”
“Yes, ma’am I do. My daddy has two penises", he says.
“What!?” the teacher says. “What do you mean your daddy has two penises?”
“Well ma’am, yes he does. He has a small one that he pees with and a big one that he brushes the babysitter’s teeth with.”
