A guy at the bar hit it off with Siamese twins. After a few drinks they headed back to his apartment.
After he made love to one, he turned and started working on the other. He couldn’t help but think that the first one might get bored watching, so he asked her what she’d like to do.
She said, “Is that a trombone in the corner? I’d love to play your trombone.”
And so she played the trombone while he had sex with her sister.
A few weeks later, the twins were walking past his apartment building. One of the girls said, “Let’s stop up and see that guy.”
The other replied, “Gee, do you think he’ll remember us?”
