Continuity mistake: In the opening scene Charles walks in and is standing next to Laverne. The shot changes and he is now sitting in a chair.
Continuity mistake: Lenny wears an Army jacket and wears a bandage around his hand because of something he did in the Army Reserve. Unfortunately, he doesn't join the Army Reserve until the next episode.
Continuity mistake: When everyone is at the couch thinking of a plan, the pillow behind Laverne changes position between shots.
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.
