If you've ever worried about leaving your house and forgetting to put pants on, then have no fear! 

For the ninth year, Boston Society of Shenanigans is bringing back the "No Pants Subway Ride".

This all started back in 2002 when a performance group called Improv Everywhere gathered together and and climbed on the subway in their underwear. Fifty cities now participate in the gag.

According to Boston.com, a Boston SOS member created a video to inform people of the event with a map an tutorial.

If you want to participate in the "No Pants Subway Ride", here are the details:

Where: 1 Pemberton Square in Boston (Look for the person with the umbrella)

When: Sunday January 10th at 2:00 pm

What: Once you meet up an organizer will give you a route card which includes what train to get on, when to remove your pants and how to move from train to train.

Don't forget to dress warm!
