Gremlin

From Encyc

A gremlin is a small, mischievous, mythical creature that likes to sabotage machinery used by humans.

Bugs Bunny faced off against a Gremlin in a B-29 bomber.

A movie was made about them in the 1980's, which included the following rules:

  • Do not get them wet
  • Do not expose them to light
  • Do not feed them after midnight
