Hyde and Shriek

From his side you might wish to escape
If you tried he'd turn vicious, the ape
And the fact is, you're stuck
With the black-hearted schmuck
Tick off Hyde, you'll be squished like a grape.

Fredric March and Miriam Hopkins in Dr. Jekyll and Mr. Hyde (Rouben Mamoulian; 1931). Title and assist by shrieking violet David Cairns, of Shadowplay.
