A guy stops to visit his friend who is paralyzed from the waist down. His friend says, "My feet are cold. Would you get me my sneakers for me?"
The guy goes upstairs, and there are his friend's two gorgeous daughters.
He says, "Hi, girls. Your dad sent me up here to fuck you."
The first daughter says, "That's not true."
He says, "I'll prove it."
He yells down the stairs, "Both of them?"
His friend yells back, "Of course, both of them."
