Couch: Repeat of the couch gag from "Guess Who's Coming to Criticize Dinner?" where Marge wipes off Matt Groening's signature on the carpet and a cartoon version of Matt Groening pops in to re-sign his scene.
Homer: Moe! The new Duff calendars are out! The ones with your picture.
Moe: Oh, boy! Move over, liquor license. (takes a framed license down from the wall)
Lenny: (reading license) Hey Moe, this license expired in 1973, and it's only good in Rhode Island … and it's signed by you.
Moe: Yeah, yeah, I've been meaning to get that updated, uh, for this state and, real.
Moe: It's hopeless, ain't it?

Carl: See what happens when you skip rehearsal?
