George's vocabulary

Sometimes surprising us!

"Mellifluous"

From "The Jacket" (S2, E3) - "We talked for like 20 minutes... She could do voiceover commercials! Why didn't you tell me about her voice?"Jerry: "I didn't notice the voice."George: "It's mellifluous!"

"Anathema"

From "The Statue" (S2, E6) - "Students can't clean. It's anathema." Jerry: "They don't like it!" George: "How long you been waiting to squeeze that into a conversation?"

Larry Charles Cameos

Writer and producer Larry Charles made four background cameos:

• "The Parking Garage" (Season 3, Episode 6): He plays the bearded passerby in the parking garage who ignores Elaine when she calls out asking for help locating Jerry's car.
• "The Trip, Part 2" (Season 4, Episode 2): When Kramer is arrested in Los Angeles as the suspected "Smog Strangler," Larry Charles appears standing in the crowd right next to Larry David as police lead Kramer away
• "The Airport" (Season 4, Episode 12): In an episode he wrote himself, Charles plays the passenger exiting the airplane lavatory after leaving behind a terrible stench that Elaine is forced to endure.
• "The Pilot" (Season 4, Episodes 23 & 24): He appears uncredited alongside Larry David in the Greenpeace raft with Russell Dalrymple (Bob Balaban) at the end of the episode.
