A guy is staying at a friends. They talk for a while and then the friend informs him of his bad leg and says how hard he is finding it living in a house with stairs, then he asks, Would you be so kind as to go get me my sneakers please?
The guest obliges and goes upstairs. There he sees his friend's daughters, both very good looking.
Being the adventurous1 and quick thinking kind, he says: Hi, ladies! Your daddy sent me here to have sex with you!
They stare at him and say, That can't be!
He replies, OK, let's check! He shouts at his friend down the stairs, Both of them?
His friend shouts back, Yes, both of them!
