John Ratzenberger is one lucky guy at the age of 65 today. He has starred in one of the most successful sitcoms ever, "Cheers". His voice has been featured in EVERY major animated movie that Pixar has released. (including his recurring role as Hamm in the Toy Story series.)
Oh, and he had a bit part in The Empire Strikes Back.
Yep, Cliff Claven was in one of the original Star Wars movies! He's one lucky sonofawookie. :)
