Did he just say...?

I was sitting at the little table with a mom and her son while he was putting together a puzzle. The little guy is 3, and totally adorable.

Little Guy: *says something I can't quite make out*

Real Librarian: *looking at LG's mom* Did he just say Chaka Khan?

LG's Mom: Huh, I think he did!

RL: Niiiiiiice!!!
