Michael Richards took 2 takes to perform the famous scene where Kramer smokes and drinks simultaneously. The first take showed Richards belching out smoke, which ended up as an outtake, so the second take ended up in the final cut instead. It was this scene that clinched Richards his second Emmy award.
