James: Teacher, that's a special jacket you're wearing.
Me: It's not a jacket. It's a shirt.
James: Really?!
Me: Yes, it's a shirt with buttons.
James: So what is that?
Me: That's another shirt. I'm wearing two shirts.
James: Isn't it hot?
Me: A little.
James: Teacher, wear T-SHIRTS, not TWO SHIRTS.
