The Red Guy's Roles: Ben Panced, Vanna Hiney
Cow and Chicken's Auntie is not seen from the waist up, just like Mom and Dad.
The Red Guy doesn't appear in "Snail Boy".
Charlie Adler was getting over a cold when this episode was filmed, which explains why Cow, Chicken, and Red Guy's voices might sound slightly off, and raspy during emphasies.
One of most creepy and disturbing scenes in the entire series is when Snail Boy poses for a nude painting. After the first airing of this episode, that scene was deleted.
You've Ben Panced? is a parody of "Wheel of Fortune".
