Michael Jackson's Glove Reason

Why does Michael Jackson wear a white glove?

So he won't bite his fingers when he eats a tootsie roll.

Explanation

This is a play on Michael Jackson's habit of wearing a single glove. The punchline creates a silly reason for it by linking it to the idea of someone being so eager to eat a tootsie roll that they might bite their fingers. It's absurd and not meant to be taken literally.
