A pregnant woman from Chicago is searching for her baby’s father on Craigslist’s Missed Connections.

The man she is looking for is a guy at the Megadeth and Motorhead concert with a red mohwak and “viper piercings”.

Obviously a man with a red mohawk at a Megadeth concert does not narrow things down, but the lady with blue hair and black biker boots does recall some intimate details.

In the post, which has been removed from the website, the woman outlines their sexual encounter in the bathroom of the Aragon Ballroom in February.

Inspired by Motorhead’s Lemmy and his hits such as Ace of Spades, the girl who does not seem to remember the father-to-be’s name has a rather blunt message for the man with the red mohawk.

“Anyway, I’m pregnant. It’s yours. Contact me if you want to be part of your child’s life,” said the post.

There has been no word on whether the star-crossed lovers have reunited.

But to a soundtrack of Megadeth or heavy metal-god-Lemmy, it might be possible to understand how they missed recalling each others names.

Bloggers on the Internet have been discussing whether the post is real, pointing to the deadpan delivery of the pregnancy news.

However, most feel that the blue haired lady has done the right thing and at least given her unborn child the chance to know his viper pierced father.

Controversial website Craigslist has had its fair share of odd, unusual and frightening stories attached to it since it launched in 1996 as a web-based service.

This month alone a personal trainer in Hollywood, Dejon Miller, was accused of using the advertising website to recruit female models and “torture” them.

Calling himself “Danger”, Miller, 35, allegedly beat and verbally abused any aspirant models who responded to his advertisements.
