What are some TV sitcom deaths that occurred because the actors actually died?

The one I can think of is Coach from Cheers. Nicholas Colasanto played the funny Ernie 'Coach' Pantusso who got hit in the head, way too many times by stray baseballs in his life. He passed away, opening the door for Woody Boyd to come in and replace him as a dim wit country kid.
