Improv Everywhere's 13th annual No Pants Subway Ride was yesterday, and it is exactly what it sounds like. In over 60 cities in 25 countries around the world, people were convinced it was a good idea to walk around in their skivvies and ride the subway—watch out for butt germs! Illustrator Paul Tuller and I took the F train (with our pants on) from 2nd Ave to to 53rd street and back down to Union Square. This is what we saw.

If you have photos of the No Pants Subway Ride in your city, send them to us. We would love to see them.
