Dirty Johnny and the Big Penis

Dirty Johnny was in the classroom, and the teacher drew a huge penis on the blackboard. She says," Can anyone tell me what this is?" Dirty Johnny stands up and says, "Yup. I know what it is. It's a penis. And you know how I know? My old man's got two of 'em." The teacher says," two of them? Are you sure, Johnny?" Johnny says," Of course I'm sure. The little one he uses to pee, and the big one he uses to brush the babysitter's teeth."
