Mates!!
 

A guy stops to visit his mate who has a bad back after a bit of a slow speed off.

His friend says, "My feet are cold. Would you get me my slippers from upstairs for me?"

The guy goes upstairs, and there are his mates two gorgeous daughters.

He says, "Hi, girls. Your dad sent me up here to sh*@ 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.";)
