CHARLOTTE, N.C. — Anyone riding Charlotte's light rail Sunday was in for a surprise.
Dozens of people hit the tracks, but left their pants behind.
This group showed up for what's turned into an international prank.
It started 12 years ago when a group of guys decided to ride New York's subways without their pants.
This year, Charlotte got in on the act and turned it into a fundraiser for the needy.
Police were standing by in case anyone got out of hand or took the prank too far.
