Revealing mistake: In the beginning of the show, Shirley is ironing Laverne's clothes and leaves the room. The iron falls on Laverne's clothes on the "L" and burns it, When she picks up the iron, the "L" is on the bottom of the iron facing the normal way when, in fact, it should have been a reverse image.
Answer: After counting to 8, the next two words are yiddish. A "schlemiel" is an inept clumsy person. A "schlimazel" is a chronically unlucky person. For example, if you are in a restaurant, and you see a waiter spill soup on a customer, the schlemiel is the waiter who spilled the soup, and the schlimazel is the guy who got the soup spilled onto him (and the schmegeggie - not part of the chant - is the doormat who gets stuck paying the check!). Hasenpfeffer is a traditional German stew made from marinated rabbit. Pfeffer is not only the name of a spice, but also of a dish where the animal's blood is used as a gelling agent for the sauce. All of it is just a silly phrasing that's part of a children's game.
