Watching the people do these insane stunts was pretty funny in general, but even some of the moments between characters were fun to watch.
- One stunt had the contestants walking down a runway... naked.
- In the Second Chances edition, the gross-out stunt was filling a cup of flies with blended maggots then drinking it. Michael Thompson, unsurprisingly, heckles everyone throughout the stunt, but the CMOF came when he was heckling Carmen, and Gina freaks out.
- Jonny Fairplay's heckling of Jonathan & Victoria. Even the other contestants couldn't bottle in their laughter."Jonathan, she's dead weight! Get a new woman, she's dead weight!"
- This bit:
Twila: I believe I might be the toughest female on this Fear Factor.Jonny: I think you might be the toughest male.- From that same 3-parter, this exchange:
Trishelle: First of all, I don't believe for one second Jonny Fairplay was a lifeguard.Joe: Maybe he was just the guy who screamed: "Whoa, dude, someone's drowning". - One stunt had contestants drinking ostrich egg. Throughout the stunt, shots of the ostriches' faces were shown looking disgusted.
- In Return To Vegas, the second stunt involved swimming with piranhas. One contestant, who is African American, reacted with "I hope they don't like dark meat."
- In "Couples Fear Factor" one contestant was trying to pull a flag, and accidentally pulled the entire pole out of the ground.
- Alison Sweeney's Freak Out when they dumped a pile of nightcrawlers on her legs.
- Penn & Teller guest starred in an episode, with Teller performing all the stunts. When one contestant was asked if she would eat a live cockroach to stay in the game, Teller, unprompted, reached into the jar and immediately ate a roach, much to the horror and disgust of the others.
