Big Bang Theory Lands Bob Newhart

Comedian Bob Newhart attends a memorial service for entertainer Andy Williams on October 21, 2012 in Branson, Missouri. Williams died on September 25, 2012 at the age of 84 after battling bladder cancer.

Bob Newhart will guest-star on an episode of The Big Bang Theory in May, marking the legend's first comedy guest spot since Desperate Housewives in 2005. (And that wasn't really a comedy comedy.) We pictured him as more of a Pawnee resident on Parks and Rec, but okay. According to TVLine, Newhart will play Sheldon's childhood hero Professor Proton, the host of a kid's science show. Your day will come, Bill Nye! Surely someone at TBBT is coming up with a plot for you as we speak.
