Now that I think if it, its very close to a couple Seinfelds. 1) Where George accidentally saves a wales and then says he's a marine biologist to impress a womand, and 2) When George gets Kramers to pose as a doctor to examine his boss and then Kramer gets a bit taken away wearing the doctors coat.
