A guy starts talking to two women in a bar. Turns out they’re Siamese twins and they wind up back at his apartment.
He makes love to one and then starts to work on the other. He thinks the first one might get bored watching, so he asks her what she’d like to do.
She replies, “Is that a trombone in the corner? I’d love to play your trombone.”
So she plays it while he makes love to her sister. A few weeks later, the girls are walking past his apartment building. One says, “Let’s stop up and see that guy.”
The other asks, “Gee… Do you think he’ll remember us?”
Thanks Michael!
