While nudity isn't an everyday occurrence on the CTA, it certainly happens from time to time--usually to the dismay of riders and CTA employees alike. But this weekend, some riders took advantage of a planned-in-advance pants-free trip.
The "No Pants Subway Ride" is a global event that was started in 2002 by Improv Everywhere in New York. Chicago of course, has not missed out on the national day of silliness.
Hundreds of pants-free people took the CTA from noon to 3 p.m. Sunday .To date, the event takes place in over 50 cities around the world.
