Here we are in Sex Education Class. The teacher says, "All right, class, I want you to go home and come back tomorrow with as many positions as you can think of for having sex."
The next day she calls on Little Johnny in the back, "Well, John, how many positions did you come up with?" Little Johnny says, "Seventy-three."
The teacher says, "Oh, my goodness...uh...very good, John, very good..."
Next she calls on Becky in the front and says, "All right, Becky, how about you?" Becky says, "Gee, teacher, I only came up with one...where the guy just lays on top of the girl."
From the back Little Johnny yells out, "Seventy-four."
