Guys catches girlfriend cheating with lesbian

I was going out with this really cute ***. She worked for TWA, Pan Am, one of those.

We got off work early one night, decided to give her apartment a ring.

You know, I call her apartment, and the number's busy.

So I wait five minutes and I call again. It's still busy.

So I figure I'd call the operator. The operator says the phone is off the hook.
