BOSTON - Don't get your knickers in a twist, but the No Pants Subway Ride is back.
Pantless participants will ride the public transit systems of Boston and other cities Sunday - a goofy ritual that's been playing out worldwide since the stunt originated in New York City in 2002.
Organizers call it "an international celebration of silliness."
Going without trousers in Boston this weekend might be a tad less uncomfortable: Temperatures are forecast to hit the mid-50s.
The latest Boston edition will start Sunday afternoon at Pemberton Square in the city's Government Center area. Riders will board the subway still wearing their pants but will strip them off once aboard.
Watch out for the pantless on subways in Atlanta, Chicago, Dallas, New York, London and elsewhere on Sunday.
