Imitation

I tell ya, some days, life imitates art.
How, You say?
Well, glad you asked:

We're getting ready for our big end of the year and doing reviews.
Several of my students got off task whilst we were going over the questions, and got their answers mixed up.There were questions like
Which one was that?
That's 12? No, 13.
14? Is that with an I?
That's true? What?
What?
What?
So, says I, "This sounds a bit like "Who's on first?"
And immediately, several students start doing the shtick...
I settle them back down and continue.
A few minutes later, from the back I hear
What?
I don't get it...
Huh?
What?
That's supposed to be a joke?

heh, some days I just have to hang my head in wonder..
