A little boy and girl go trick or treating.

They knock on the door.

The man who answers says, "Well, you two are awful cute. Who are you supposed to be?"

"We're Jack and Jill" they answer.

The man says, "You can't be Jack and Jill, you're black."

They go off, come back, dressed differently.

The man says, "Well now this is just darn cute.

Who are you this time?"

"We're Hansel and Gretel."

"I hate to disappoint you" says the man, " but you can't be because you are black."

Heads hung low, they leave.

Not much later the man hears the door bell ring again.

This time when he opens the door, there stands the two children ... buck naked.

"Oh my! And just who are you supposed to be now?"

"We're M & M's" said the little girl.
