Setting the scene: The teacher is seated at a desk at the front of the room, surrounded by students (mostly girls) asking for help on a particularly difficult question from the textbook.
Food and drinks are not allowed in the classroom. A boy (let's call him Steve), carrying a bag of candy, sidles up to the desk, hoping that if he offers some to the teacher, that he will be allowed to eat the rest.
Steve: "Miss, would you like some Reese's Penis?"
Teacher (without missing a beat): "Thanks for the offer, but I think I'll pass."
Steve: "Oh...wow...um...uh..." *girls overcome shocked silence and begin to giggle uncontrollably*
Teacher: "It might be best if you go sit down."
Steve: "Um...yeah...okay... *wanders off*
