Why did the black cat join a trick-or-treat group?

Because it wanted to purr-fect its costume and get some paws-itive candy

Why did the mummy always use fabric softener?

Because he didn't want any more static cling with his bandages!

Why did the candy go to the doctor?

It was feeling a little sour!

Why did Medusa finally get a haircut?

Because she was tired of all her split ends turning to stone.
