A man walks into a hotel lobby. He wants to ask the clerk a question and
  as he turns to go to the front desk, he accidentally bumps into a woman
  beside him, knocking his elbow into her breast. They are both startled
  and he says, "Ma'am, if your heart is as soft as your breast, I know you
  will forgive me." She replies, "If your penis is as hard as your elbow,
  I'm in room 1221."
