Scenes from a Kentucky superstore

Teenage boy holding a slim red book: This ain't a dictionary, mom. It's a thee-a-saurus.
Baffled looking mom: Wut?
Boy: A thee-a-saurus.
Mom: What's a thee-a-saurus?
Boy: It's like words that are almost the same.
Mom: It's wut?
Boy: A thee-a-saurus. It lists words that almost mean the same thing. It ain't a dictionary.
Mom: Then put it back.

I don't make this up.
