What's Cookin' Doc? is a 1944 Warner Bros. cartoon in the Merrie Melodies series, directed by Bob Clampett, and stars Bugs Bunny. The short was also written by Michael Sasanoff, and was animated by Robert McKimson, along with uncredited work by Rod Scribner, Phil Monroe and Virgil Ross. The film was released on January 8, 1944. The title is a variant on Bugs' catch-phrase "What's up Doc?". It also hints at one of the scenes in the picture.
