On the boards lately, we've had a clamoring for relatives and I'm wondering what actors should play the ones we haven't met yet. So who would you like to see play Sheldon's mee-maw/brother, Leonard's father/brother/sister, Penny's mother/brother/sister, Howard's father, Amy's father, or anyone else I've omitted?
I'll start with something I mentioned on another thread. Kelsey Grammer would be a natural choice to play Leonard's father. He looks the part and besides, Leonard's father has been described as being similar to a Frasier Crane type character.
