Silliness

I've heard this response way too many times in just the first month of teaching here:

Me: Alrighty class, I'd like you to please _____(insert any command involving work, school, biology, life, personal hygiene, etc.)______.

Students: R U SERIUS????

Well of COURSE I'm joking students! After all, all we teachers do is lie to you! That's the whole point of education!

Oh, Mr. Smyr, you silly, silly bitch.
