Stan tries to get Jeff to develop his own personality by having him join the inner circle of celebrity chef Guy Fieri, only to learn that Fieri isn't what he seems. Meanwhile, Roger and Klaus become valets.
Tropes:
- Affably Evil: The Fieri demon possesses people and uses their bodies to eat everything it can get its hands on, but it's also friendly with Stan, who admits he likes the demon more than Jeff.Stan: For Jeff to come back, Guy Fieri has to die? But I like you way better than Jeff!Fieri!Jeff: You...are a true G.(The two fist bump)
- All Just a Dream: Turns out that Roger and Klaus's plot was a comic book that Steve was reading.
- Big "NO!": Stan belts this out when he finds that Fieri really is gone and Jeff is back to normal.
- Demonic Possession: Stan learns that Guy Fieri is actually an ancient demon who possesses people in order to eat every flavor imaginable. Once diabetes kicks in, it moves on to the next host.
- Epic Fail: Roger is confronted by customers who ask for their cars back, only to say that they just park the cars and don't actually keep track of them.
- Evil Sounds Deep: Fieri!Jeff develops a deep, demonic voice once he finds the source of his power.Stan: Wow, are you full demon now?!
- Forbidden Fruit: In Flavortown, there is a pool of spicy habanero-mango infused queso, described as "the first element of God's creation." The Fieri demon is unable to eat it because doing so would destroy him, but Stan tricks him so that Jeff can come back.
- I Just Want My Beloved to Be Happy: Stan likes the Fieri-possessed Jeff much more than the actual Jeff, but has to destroy him so that Hayley can be happy.
- Large Ham: Guy Fieri already is one, but the demon takes it to untold levels."I've called things money before, but this...is...MOOOOOOOOOONNEEEEEEEEEYYYYYYYYYYY!!!"
- My God, What Have I Done?: Stan immediately regrets tricking the Fieri demon into eating the queso."He wasn't a demon! He was an angel!"
- Reverse Psychology: Stan tricks the demon into eating the queso by failing to describe it.Stan: (tastes the queso with his pinky finger) Wow!Fieri!Jeff: I knew it! Tell me how it tastes!Stan: (beat) It's good.Fieri!Jeff: Give me more than that, brother.Stan: Well, it has a yellow-y, kind of melted taste.Fieri!Jeff: Your words fail you, mortal!Stan: Oh, I know now. It doesn't taste like paint!Fieri!Jeff: What the hell does that even...GET OUT OF MY WAY!!!
- Right in Front of Me: Stan reads in the book that the host body must be washed in the source of the demon's power and wonders what the source is, right before finding Fieri!Jeff standing at the source.
