Every year, at the end of the summer, the city of Philadelphia hosts a festival showcasing various artists and performers. People from all over come to see the Philadelphia Live Arts Festival. Back in 2005, the festival began with an interesting event- a toilet tricycle race.
To participate, artists created a form of transportation using a toilet and a tricycle. I suppose using a one-piece toilet would be the option because the artists can't attach it to anything but the tricycle. Too bad the race only happened one year, it would be very interesting to see a group of toilet tricycle racers.
