Encounters I Didn't Understand

I was at Six Flags Magic Mountain over the summer with three of my friends. It was 98 degrees and disgustingly hot. As we were standing in line buying tickets a bus pulled up and about 20 people dressed as clowns got out of the bus. They had the face paint, the huge shoes, the works. They got in line to buy tickets as well. We asked them why they were dressed as clowns and they simply replied why not. My friends and I saw them at least five other times during the day and the last time we saw them all their face paint was coming off and they look tired and wore out. I didn't understand why anyone would want to spend a day at Six Flags as a clown.
