Does Eddie Haskell say Ce si le bon?

Eddie Haskell from "Leave It to Beaver" never says "Ce si le bon" in the show. He's known for his sly, manipulative ways and phrases like "Gee whiz, Mr. Cleaver!" and "How about a little 'ol somethin' somethin' for your troubles, Mr. Cleaver?"

The phrase "Ce si le bon" is French and means "This is the good one" or "This is the right one." It's not a phrase that would have been commonly used in 1950s America, where the show is set.
