The Siamese Twins and the Trombone

A man meets two women at a bar who are Siamese twins: Suzie and Cheryl. He buys them a few drinks and they wind up back at his place. After a few more drinks he starts to make out with Suzie. Realizing Cheryl might get bored, he asks her, "Is there anything you would like to do?"

Cheryl says, "I see a trombone in the corner; I'll play that!"

The night continues with the man having sex with Suzie while Cheryl plays the trombone.

A few weeks later, the Siamese twins are walking past the man's apartment. Suzie says, "Do you think we should stop and say hello?"

And Cheryl says, "I don't know, Do you think he'll remember us?"
