Aqua Unit Patrol Squad 1

In this episode, Carl claims he calls the cops to have them come over, but they took one look and kept driving, but Carl has said in previous episodes that the cops don't answer his calls.

Earlier in the episode, Carl said he called the cops, who took one look at Paul and took off. Later on, there is a bunch of cop cars around the house, even though they were supposedly too afraid to want to deal with the monster.

After Frylock discovers that someone else has moved into their house Carl says "it has actually been rented a few times" referring to the robots in "Robots Everywhere" and the sirens in "Sirens".
