also Busy Phillips as Penny's cousin or sister

Oh fun idea lets see, in no particular order:

- John Goodman (As Penny's Dad XD)
- Seth Green
- Leonard Nimoy (Just to see Sheldon freak out lol)

And of course!
- Bill Nye The Science Guy

BETTY WHITE

I would love to see Leonard Nimoy on the show. I also think there HAS to be an episode with Memaw!! Click on my link above to join my Facebook campaign to get Sheldon's Memaw to make an appearance!
