Triumph of the Wilbur

What's contained 'neath his pate isn't grand
But his brain's in the greatest demand
With a will unreliable,
Little Wilbur is pliable,
Can be trained to obey your command.

Wilbur Grey is hypnotized by Dracula, who plans to put his submissive brain into the Monster: Béla Lugosi and Lou Costello in Abbott and Costello Meet Frankenstein (Charles Barton; 1948).
