No Pants BART Ride Day Featured in
Since 2001, the Annual No Pants Subway Ride (No Pants BART Ride Day) takes place every January in San Francisco. In case you were wondering, BART stands for 'Bay Area Rapid Transit'. Over 600 people ride BART without any pants but only in colorful undies and socks. The main idea is to keep a straight face and act normal. Usually, people can't keep themselves from chatting, joking and taking pictures.
The No Pants BART Ride also takes place in dozen of countries around the world. It was initiated by prank group Improv Everywhere. This event happens spontaneously in early January. The date is usually selected in early December. The first No Pants Subway Ride took place in New York City with 150 people participating. By the way, some participants were handcuffed for disorderly conduct.
