A man is in a hotel lobby and 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 his elbow pokes her in the breast. They
are both quite startled.

The man turns to her and 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 436."
