For the first joke they had a contest to see who can last the longest without masturbating. Kramer was first "out". Yeah, without knowing that, it kinda doesn't make sense...
Also:
Rodney: We're starting in the Self-Catering Holiday trade.
Del: On 200 nicker?
Rodney: We're starting off in a small way.
Grandad: What you got, a Wendy House?
Sorry bout that. I just assume everyone would understand as everyone I know personally and everyone on every forum I have been a part of from every country around the world seems to have seen every episode of Seinfeld repeatedly.
Just seen True Lies (first time in english though )
"Doris" aka Jamie Lee Curtis said: "I married Rambo!" after "Boris" aka Arnold Schwarzenegger has released a couple of supporting actors aka "Crimson Jihad" off their duties. Had to giggle (just a little) about that one.
Sorry, its not a TV series, will remove it if requested.
