A day off to look for beetles

Miss Crazy having a conversation with Mr Handy last Friday

Miss Crazy: It's a long weekend this weekend, isn't it?

Mr Handy: Is it, why?

Miss Crazy: We're not going to school on Monday. It's beetle day.

Mr Handy: Beetle Day?!?

Miss Crazy: Yes, beetle day. No, I mean, Insect day.

Mr Handy: Do you mean INSET day?

Miss Crazy very confused
