Homestar Runner Wiki : Where's the Cheat?/EasterEggs

"Where The Cheat is at?" is a reference to "Where my hat is at?", an old Homestar thing that was "Homestar's World Wide Web Debut".
The car Strong Mad lifted up is the Gremlin from "Homestarloween Party".
When the The King of Town is walking towards his grill, a flyer for The Cheat is seen stapled to his stone castle wall.
Right before The King of Town comes up when Coach Z is talking to The Poopsmith, Coach Z quickly changes his hand gesture, if you look closely they accidently left the graphic for his other gesture there for a couple frames.
When Coach Z attacks The King of Town, the The King of Town's crown flips up on Coach Z's head.
The little green dancing thingy that Strong Mad finds under the Gremlin is The Goblin from "Homestarloween Party".
