Once competed on family game show I'm Telling! (1987) with sister Marissa Ribisi.
Clashed with filmmakers on the Basic (2003) set because of the inclusion of a female Special Forces operative. Women are not eligible for combat in the US military. He felt it compromised the integrity of the story.
First appeared, uncredited, on Friends (1994) in Friends: The One with the Baby on the Bus (1995) at the end, as the guy who had dropped a condom in Phoebe's guitar while she was singing in front of Central Perk (because the manager hired a professional musician). Later that season, he came back in Friends: The One with the Bullies (1996) as "Frank Buffay Jr.", Phoebe's younger half-brother, a character that stayed for 8 episodes over several seasons.
He is 15 minutes older than twin sister Marissa Ribisi.
Was approached to play "Lynch McGraw" in Hero Wanted (2008) but turned it down.
