Professor Krassman is a German mad scientist who appeared in The Muppet Movie. Employed by Doc Hopper as part of his on-going campaign to obtain Kermit the Frog as commercial spokesman, Krassman is the world's leading authority in the rapidly growing field of mind control in frogs.
The result of many late-nights at his laboratories in Cologne and Dusseldorf, his latest achievement is an imposing device for use in performing an electronic cerebrectomy, a process by which a frog's brain is reduced to guacamole. The electronic yarmulke is attached to the patient's head. Due to the timely intervention of Miss Piggy, Kermit's gray matter is saved, and Krassman becomes a victim of his own devices.
