Julia's career-ending dancing
The writers thought that Julia Louis-Dreyfus' dancing were so painfully bad, they'd end her career!
Reflecting on the Season 8 episode 'The Little Kicks', which showcases Elaine's less-than-impressive moves, 'Seinfeld' writer Spike Feresten revealed that Larry David thought including the scene was a big mistake.
He said: "I remember walking through at rehearsal. “[Writer-producer] Jennifer Crittenden pulled me aside after Julia did the dance for the first time and said, 'Are you sure about this? Are you sure you're not ruining Julia Louis-Dreyfus' career?' 'No, I'm not.' That's the year she won an Emmy.”
