A mummy pulls into a gas station and says: “Fill it up.”
The attendant steps around to the driver’s side, unscrews the cap, and starts pumping gas. When he’s done, he says to the mummy: “That’ll be fifty bucks.”
The mummy is annoyed and says: “I said to fill it up. You’ve only done half the job.”
“What’re you talking about?”
The mummy points to the passenger side. “This car has a second gas tank.”
“Oh really,” says the attendant. “And why’s that?”
“Because I’m a two tank car man.”
