Monsieur Cousteau Begs To Differ

On the way to school this morning we were discussing where the various characters on Sponge Bob Squarepants live - pineapple, statue, rock, etc. C said that Mr. Crab lives in an anchor.

Me: You mean he lives on an anchor.
C: No, in an anchor.
Me: You can't live in an anchor.
C: It's a cartoon.
