Miss Finster: Okay class, it's time to talk about The War of 1812.

Squaro: Miss Finster, we have a question.

Circly: What do you get when you cross a snowman and a vampire?

Miss Finster: I don't know.

Squaro and Circly: Frostbite! Ha ha ha ha ha ha ha ha ha ha ha ha ha ha!

Miss Finster: Squaro and Circly, how dare you interrupt class to tell a joke?! That's it! Go to the principal's office now!

Squaro: Queen Lanolin, this is the 12th time we meet.

Queen Lanolin: That's right. Also, do you know why you both were called here?

Circly: We told a joke during class.

Queen Lanolin: Squaro and Circly, we don't tell jokes during class! That's it! Instead of giving you both a Suspension Level 23, I will give you both a Suspension Level 24! Get out of here right now!
