11) Alec Baldwin (Parker) – Season 8, Episodes 17 and 18

Alec Baldwin appeared in The One with the Tea Leaves, and, The One in Massapequa as Parker, Phoebe’s overly cheerful boyfriend. Parker’s personality was so over-the-top that he instantly stood out. He praised everything, from coat hangers to subway tunnels, leaving the group uncomfortable. Baldwin made Parker’s energy feel natural, never letting it cross into cartoonish territory. His exaggerated compliments and constant enthusiasm made scenes both funny and cringeworthy. The Massapequa episode, where he fawned over Monica and Ross’s parents’ anniversary party, pushed the character’s quirks even further. Baldwin’s ability to make Parker likable despite his exhausting personality made these episodes memorable.
