Historically, people have tried everything to find a compatible mate. From hooking up at the office Christmas party, to internet dating, to letting one’s friends play matchmaker, just about everything has been done in the name of love. Although you’d think all strategies had been exhausted by now, you would be wrong. What’s more, one of the newest and definitely wackiest ways of locating a mate actually has the most scientific merit.

Enter the sweaty t-shirt party. The brainchild of 25 year old rapper and web developer Judith Prays, the concept is that people will attend a party and bring a recently-worn t-shirt. The t-shirts are placed in numbered, reseal able bags. Folks of the opposite sex open and smell the contents, and select potential dates based on their gut reaction to the smell. The idea behind this is that people will naturally pair up based on pheromone responses.

The idea is quickly gaining traction. The first sweaty t-shirt party took place in New York and has already spread to Los Angeles. Although scientists note that these parties lack the control factors of a bona fide scientific experiment, attendees are reporting the start of lasting relationships. There’s no report yet on how many party attendees did a load of laundry after the event.
