One funny moment happens in Follow My Footprints, despite being a bit of a Mood Whiplash given the plot of the episode: Moe Skeeter and Lars Vegas trying to figure out how to steal Leonardo da Vinci's The Last Supper.
Moe Skeeter: Uh, Lars, the painting's on the wall.
Lars Vegas: Right, so what do you need? Bolt cutters? Screwdrivers?
Moe Skeeter: No, it's on the wall.
Lars Vegas: Of course it's on the wall! This is a museum!
Moe Skeeter: No, it's a fresco!
Moe Skeeter: No! The painting's a fresco!
: Noo! The painting's a da Vinci, you witless insect
! So how are we gonna take it?
Moe Skeeter: We're not! It's a fresco! And that means it's painted on the wall!
*Lars takes out a flashlight to examine The Last Supper*
Moe Skeeter: I told you it was on the wall.
