Group plans latest pantsless subway ride

If you see someone in their underwear, don’t worry.

On Sunday, $2.50 will get you a subway ride and a peep show when the ImprovEverywhere group holds its 14th No Pants Subway Ride.

The “prank collective” is organizing groups of people to get on a train, take their pants off and go for a ride with a straight face. The ride lasts from 3 to 5 p.m., with seven staging areas in Queens, Brooklyn and Manhattan neighborhoods.

ImprovEverywhere is also organizing the ride on Sunday in subway systems around the world, including London, Mexico City and Sydney.
