Chased by the "Cups"

I pick Sam up from camp every afternoon at 12:45. This is the conversation we had when I pulled up to the carpool line today:

(Brittany, Sam's favorite camp counselor, opens Sam's car door and helps him into his seat.)
Sam: Mrs. Allison! I got chased by the cups today!!!
Me: Oh! You got chased by what?
(Brittany and I look at each other and giggle.)
Sam: The cups! My friend Brandon was a police officer and he chased me around but I ran away from him. I ran away from the cups!
Me: Do you mean you ran away from the cops?
Sam: No...the CUPS!

He's the funniest kid in the whole white world.
