I'm in Room 1221

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 1221.”
