Count Draculations!: Monster Riddles compiled by Charles Keller, 1986.

This is one of those themed joke books for kids that has monster and Halloween-themed jokes.  The jokes are the basic kid-friendly question-and-response type with lots of puns.  There are also some cute black-and-white illustrations.

Some of my favorite jokes:

Why do witches get A’s in school?

Because they are good at spelling.

How do you get into a locked cemetery?

With a skeleton key.

Why did Frankenstein’s monster go to the psychiatrist?

He thought he had a screw loose.

Why did the invisible man go crazy?

Out of sight, out of mind.
