A Joke, About Hand Lotion

So this woman I work with came up to my desk, held out her hands and said, "I put too much lotion on my hands, do you want some?"

I grinned, looked down and said, "I could make a hell of a joke here, but no thanks."

She laughed and went away. She didn't get it. Good thing I didn't proceed with the joke, she is my boss now!
