What we didn't know is that Michael Richards injured himself when he taped that scene. Here's what an article on skinny jeans says:
'Jerry Seinfeld poked fun at slim-fitting jeans in a 1996 episode of "Seinfeld." The Kramer character barges into Jerry's apartment wearing a pair of jeans so tight he is forced to adopt an unnatural walk. When Kramer has trouble taking off the jeans, Jerry tries to yank them off by the legs. The actor playing Kramer, Michael Richards, injured himself slightly during the filming of that scene.
"As Jerry recalls, it was just a minor little muscle spasm that annoyed him for a couple of days," says Mr. Seinfeld's publicist, Elizabeth Clark Zoia. "But they made our point about men's jeans that require too much effort."'
