One of the offerings in this year's annual Christmas catalog from Neiman Marcus is a "Customized Cupcake Car" available for $25,000.
Also, if you weren't convinced that Burning Man has jumped the burning shark, then check out the blurb from the catalog:
Launched at Burning ManSM as a cooperative art car project, the Cupcake Car sprang from the fevered mind of Bay Area artist Lisa Pongrace and her less-rules-more-laughs posse of artists and techno geeks. Yours will be tricked out with your favorite topping, so start thinking flavors.
Note the SM or "service mark" after Burning Man. It should say "SO" for sell out. OH! BURRRRN!
