Two drunk guys stumble out of a bar and get into their car. After they've been driving for a while, they see a ghostly face appear at the window.

"It's a ghost, dude!"

"Roll down the window, ask him what he wants!" The driver rolls down the window, and asks the ghost.

"You got a smoke?" They give him a smoke, and the face goes away. A few minutes later, the face returns.

"You got a light?" They give a light, and the face goes away. A few minutes later, the face returns.

"You guys need help getting out the mud?"
