Hey fellas, did you recently hook up with a chick at the Chicago stop of Megadeth's Gigantour? If so, you may be a new father! A woman in the Chicago area recently posted an ad on Craigslist looking for the father of her unborn child, who was apparently conceived in the beautiful Aragon Ballroom bathroom stalls.

Hold on, hold on, before you start freaking out, think of how many people were at the show. Thousands of people were at that show. You couldn't have been the only one making sweet music in the bathrooms… right?

Okay, things aren't looking good -- but the knocked up metalhead posted a detailed description of the anonymous donor within her Craigslist ad:

Me: Blue hair, silver tube top, Knee high black biker boots.
You: Red mohawk, black pentagram gauges, viper piercings.

I was grinding on you in the pit, then we went to the bathroom, and got f---ed up. You had a nice c--k and I was wasted so I let raw dog it in the stall. You were really good and you had to gag me so I would make too much noise.

Anyway I'm pregnant. It's yours. contact me if you want to be a part of your child's life.

The Craigslist ad has since been taken down, so you may be off the hook! The only thing you need to worry about now is getting a call from Maury Povich.
