"Bad Hare Day" is the first segment of the fifteenth episode of Brandy & Mr. Whiskers.
When Brandy has a red scarf and she wants to wear it to meet her friend's parents and tells Mr. Whiskers not to touch it (or risk getting fed to the lions). Whiskers takes it without Brandy knowing and he messes it up when it goes into a volcano. Ed has an idea to weave a new scarf out of Whiskers' fur, so they use bugs to shave it off (in the process he has to take off his jumpsuit), and a special formula to regrow his fur, however his fur keeps on growing longer and longer so he tries to fool Brandy into thinking it's growing strangely because he's old.
- Whiskers' age is mentioned only in this episode.
- The title card is based on that of the 1946 Bugs Bunny cartoon Hair-Raising Hare.
