In AP Bio, as in every Biology class that's ever been taken, we had a unit on anatomy, broken down into smaller units. One of the first ones we covered, back in early April, was human reproductive anatomy.

So, second period, early April, Reproductive Anatomy unit, and the teacher has a slide showing the female reproductive system up on the projector. All is going fairly well, if a bit boring, when I hear the guy at the table behind me call out to the teacher "I have a question!"

I stop my doodling, anticipating the question to be something amusing, but not quite as amusing as what actually came out.

"If a girl has... Two holes... Down there? Right, there's the...urethra and then the other one is separate-"

"Yes?"

"What if you were having sex with a girl- Could you put it in the wrong hole accidentally?"

The teacher was gaping at him at this point, and I, still controlling the urge to laugh, looked around the room to see that a few other people were looking towards the front expectantly, obviously wondering the same sort of thing. Our teacher valiantly continued.

"The wrong hole?"

"Yeah, the wrong hole. I mean, could you accidentally stick it up the urethra?"

To which the teacher laughed a little and said:

"I think it would more likely go up the anus, though neither are very likely."

The look on the boy's face, not to mention half the faces in the AP Biology class, could only be described as one of shocked revelation.

"It can go up there?"
