* CatDog winning against the Greasers in a surfing contest.
* The CatDog wheel.
* Cat completely losing it and destroying everyone in "Monster Truck Folly".
* The end of "Brother's Day." Winslow tried to set up a GiftOfTheMagiPlot, with Cat selling his luffa sponge to buy Dog a mud-wrestling costume and Dog selling the mud from his ring. However, instead of the luffa carrying case, Dog bought Cat a mud-wrestling costume, too. After Winslow expresses disappointment over this turn of events, Cat and Dog don their costumes and tag-team him as payback.
-->'''Dog:''' Looks like it's curtains for the little blue guy!
* Cat's prank in "Kooky Prank Day," which is so complex (involving an alien invasion and robots) that to pull it off perfectly is awesome in and of itself.
