Post some conversations that either really happened or you made up, and then let people guess if they are true of false. There's no need to wait for responses to pose another conversation, just quote the one you are responding to.
Here's my first one:
Once very late at a party and back in one of the bedrooms, a girl asked me a little put off, "Why does your dick taste like cigarettes? I didn't think you were a smoker?"
I was at a loss of what to say, so I just blurted out, "I'm not a smoker. That girl that blew me a couple hours ago is, so you must be tasting her. . . . "
