From the article: It should be noted this second that “Swiss cheese” is what we call Swiss cheese, but the Swiss, being Swiss, make many cheeses, and do not call them all “Swiss cheese.” What we know as “Swiss cheese” is called Emmental in Europe.
He does ask for Emmental along with Gruyere, so the skit does not have a hole in it.
LOL, I guess I need to brush up on my cheeses.
