I saw every episode of "Seinfeld", in its original run and up to today in syndication, and I don't recall seeing him in any episode. I doublechecked at the IMDb, and his record there confirms my memory--it doesn't list any appearance on "Seinfeld."
You might be thinking of the "Festivus" episode. In that episode, Elaine had given the number of an off-track betting parlor as her phone number, to ditch a guy who hit on her. One of the clerks at the OTB resembles Jack Black, but is not Jack.
The episode that Jack Black appears in is "New Friends" in season 2 episode 30, original air date was 3-3-09.
No. Many stars were in episodes of Seinfeld over the years, but not Cameron Diaz.
Dyana Ortelli is credited as Lupe the chambermaid so NO D.Moore does not appear in The Trip part 1 or in any other episode of Seinfeld for that matter yet- there is a discussion about spelling of her name in the episode The Secretary S6E9
I swore that was him in the "Serenity Now" Seinfeld episode, however I found out its actually Ross Malinger (who played Jonah on "Sleepless in Seattle"). Wow he looks a lot like Jett!
You may have Jack Black confused with Tyler Labine who played Ray's Chef in the Royal Pains Season 6 episode called, Everyone Loves Ray, Man.
The final episode of Seinfeld aired on May 14, 1998.
The episode is called "The Bubble Boy" it is the 7th episode of the 4th season of Seinfeld.
Almost. There is a batman in every episode of Seinfeld!
The episode that Jack Black appears in is "New Friends" in season 2 episode 30, original air date was 3-3-09.
Superman. He either had the magnet on his fridge or he had a statue on his shelf
He absolutely was! A season 3 episode called "D.P.O."
Season 7 episode 11
Season 3 episode 4 (the dog)
She was in the very first episode.
The Pen episode!
There were black folk on Seinfeld?!
Season 9 Episode 10. This episode is title "The Strike"
