A man is in a hotel lobby.
He wants to ask the clerk a question.
As he turns to go to the front desk, he accidentally bumps into a woman beside him and as he does, his elbow goes into her breast.
They are both startled and he says, “Ma’am, if your heart is as soft as your breast, I know you’ll forgive me. “
She replies, “If your penis is as hard as your elbow, I’m in room 5421. “
