Greystash's defining feature is his impressive mustache, several feet long on each end and endowed with special powers. When Homer skipped to the end of the final book and discovered Greystash was killed by the evil wizard Malicious Krubb, he invents a happier ending for Lisa. In this new ending, Greystash says "mustache powers activate", granting his mustache powerful muscles. The evil wizard is clobbered to death, and Greystash saves the day. However Lisa kept another copy of the book under her pillow and read the real ending but decided Homer's ending was better.
Maggie once dressed a costume of him.
Behind the laughter Edit
- Greystash is a parody of Albus Dumbledore in the Harry Potter book series.
- Headmaster Greystash is much like Albus Dumbledore. They are both incredibly old and are both incredibly wise, and both died a hero's death as they both sacrificed themselves to save the main characters.
- Greystash was killed by Malicious Krubb, like Dumbledore was killed by Severus Snape in Harry Potter and the Half-Bood Prince.
