Three male friends go to the store.

They all need to use the restroom, and decide to go in one at a time.

The first man enters the stall, sits down, and is about to do his business when he hears a voice.

"I AM THE GHOST OF BLACK PAPER!"

The man runs out and says to his friends, "There's a ghost in the bathroom! One of you have to go check it out."

"Okay, I got this," says one of his friends before he heads to the bathroom.

He enters the stall, sits down, and waits. Soon enough, he hears a voice in the bathroom with him.

"I AM THE GHOST OF BROWN PAPER!"

He runs out of the bathroom like his friend had, and approaches the other two.

"You're right, there is a ghost in there! Go in and check it out!"

The third friend sighs and agrees to go.

He enters the stall, sits, does his business, and waits...

"I AM THE GHOST OF WHITE PAPER!"

The man quickly retorts, "Oh yeah? Then give me some to wipe my ass with!"
