Flap that tops off his mind-box is flat
If he drops by, he finds that folks scat
When a Wolf Man befriends him,
Arms he fully extends him:
The brain-swap's left him blind as a bat.
Lon Chaney Jr and Béla Lugosi pose for Frankenstein Meets the Wolf Man (Roy William Neill; 1943). Title by always hell-pful David Cairns.
