Halloween Joke Thread

Our neighborhood has the trick-or-treaters tell jokes before getting their treats. We thought it was strange the first couple years we lived there, but after almost 20 years, its gotten to be fun.
Here are my donations:

What happened to the guy who didn't pay his exorcist?
He was repossessed


What do baby ghosts wear on their feet?
Boo-ties!

What is a skeleton's favorite song while riding his Harley Davidson motorcycle?
Bone to Be Wild!
