Floating on the moon
The Bus lands on the moon, but everyone's floating around as if they were in space. Never mind that the moon is supposed to have one-sixth the Earth's gravity. Also when they were in space, they were just sitting at their seats instead of floating.
Deedee: Knock Knock.
Mudge: Who's there?
Mudge: Ivan who?
Deedee: Ivan a new pair of sunglasses at a contest. Aren't they cool? (giggles) Get it? I won a new pair of sunglasses. (laughs)
Mudge: (looking at audience while pointing at Deedee) She's been out in the sun too much.
Moosehead: It's time to vamoose! I like any word with moose in it.
Moe: On the moon we can yell as loud as you want.
Rooney: Moe, we aren't on the moon.
