When things are slow at the comic shop:
(Mike and pal Dorian are discussing the phrase “mouse heaven” from the instruction manual for the Atari 2600 version of Mouse Trap)
M: “So, would mouse hell be cat heaven?”
D: “Yes, and cat hell would be dog heaven.”
M: “There is a certain economy to that.”
D: “But what would dog hell be?”
(a moment passes)
M: “I think the default hell for any animal at the top of these progressions would be ‘shark heaven.'”
