|Cartoon Network US Premiere||September 7, 2001 (when it was a part of a Grim & Evil episode), 2003 (when it was a part of a The Grim Adventures of Billy & Mandy episode)|
Fiend is Like Friend Without the 'R'
After watching a movie, Grim teaches Billy to possess people by jumping into their heads. Then, Billy possesses Mandy, and makes her do assorted things like flirting with Irwin, kissing Mandy's mother, going into both men's and women's restrooms, and eating earthworms. In the end, Billy leaves Mandy's head, but later that night, Mandy possesses Billy's cat, Milkshakes, to maul him.
QuotesBilly: Ew! That soaks! This will be so scary!
Grim: Oh, believe! I've seen scarier stuff in your toilet!
Billy: Yeah... Hey, can you jump in people's heads like that too?
Grim: [singing, while in Milkshake's (Billy's cat) body] Look at me, I'm a kitty cat! I wear a bowl of peanuts for a hat. If I eat them all, I will get fat. Blah blah blah, I'm a kitty cat!
Mandy: What are you doing, you brainless monkey?
Billy: (as Mandy) Hey, Irwin!
Irwin: Uh... Hi, Mandy.
Billy: (as Mandy) You are such a cutie!
Irwin: You all right, mate?
Billy: (as Mandy) Yeah, you'll rock! [laughing]
Mandy: (as Milkshakes) You know, Billy, you can pick your friends and you can pick your nose. But you can't pick your friends' nose.
- This is Irwin's first appearance, and possibly the reason behind Irwin's crush on Mandy, since Billy flirted with Irwin while in Mandy's head.
