Elbow memes

What can you hold in your left hand but not in your right?

Answer: Your right elbow.

My poor knowledge of Greek mythology has always been my Achilles' elbow.

A man accidentally elbows a woman's boob as she is standing behind him in a hotel lobby. The man apologizes profusely and says, "If your heart is as soft as your breasts, I know you'll forgive me."

To which the woman replied, "If your dick is as hard as your elbow, I'm in room 318."
