There's a Mystery Machine sitting outside Andrew Borakove's nondescript warehouse on a quiet street in Lincoln, Neb.
"I can never be depressed driving around town, because there's always some 4-year-old waving to me manically," Borakove says.
The mystery about the Scooby Doo replica van starts to fade, however, once you notice the bumper stickers on the back. Black background, white font, like a "Got Milk?" ad: "Happiness Is a Warm Gong." "Gongs, Not Bongs." "My Child Is an Honor Gong Player."
