Paul Rudd
These days, everyone loves Paul Rudd. Once upon a time though, he was just a young actor new to the industry. He played Phoebe's boyfriend turned husband in seasons 9 and 10. Mike Hannigan is definitely one of the best boyfriends of the entire show!
Charlton Heston
Charlton Heston was one of those rare cameos who got to appear in the famous series as himself! The signature tough guy act got the royal treatment when he appeared in season 4 alongside Matt LeBlanc. The duo was a comedic crack-up!
