What's Cookin' Doc? is a 1944 Warner Bros. cartoon in the Merrie Melodies series, directed by Bob Clampett and starring Bugs Bunny. The story is credited to Michael Sasanoff and the animation is credited to Robert McKimson, although Rod Scribner animated on this cartoon as well. The title is a variant on Bugs' catch-phrase "What's up Doc?". It also hints at one of the scenes in the picture.
