A Bird in the Head (S)

The stooges are working as paperhangers in the home of Professor Panzer, a mad scientist looking for a brain to use in his experiments. The professor wants to put a human brain into a gorilla but has trouble finding a brain small enough, which leads him to select Curly as the perfect donor. The stooges manage to foil the madman with the help of the Gorilla who befriends Curly.
