People will be riding the red line this weekend without pants in honor of the No Pants Subway Ride. Here's more from Curbed Chicago:
"The event, dedicated to pure silliness, was started in 2002 by a group of performers, Improv Everywhere. On that first ride, seven pants-less people got on a train and pretended not to notice each other for a few stops, and eventually someone hopped on board the train selling pants for $1.
"In following years the event took off after word of mouth spread and a few stories from news outlets including This American Life covered Improv Everywhere. Last year, 60 cities participated including places outside the U.S. like Amsterdam, Lisbon, Prague, Munich, and Brisbane. The absence of a subway didn’t stop people either, the ride took place on trolleys, buses, and light rails too."
