Spit Happens is a Simpsons Comics One-Shot Wonders story that appears in.

Plot
Kang and Kodos are tired of their constant drooling on the spaceship. So, they go to Earth to find a human with brain cells to find a solution to stop them drooling. They beam Professor Frink on board to get him to help them. They then tell Frink that if he helps them build a device to stop them drooling everywhere, they won't horrifically devour him, probably. Frink designs a saliva removal device but the aliens are unimpressed as it'll eat up their entire energy budget. His next idea is a spit tank, which collects up their saliva and stores it out of sight. However, Kang and Kodos don't like it as they think the tank is hideous. They then give him one more chance to find a solution. Frink then suggests they use a mop to clean it up which leads to Kang and Kodos returning him to Earth and then kidnapping Willie with his mop to help.
