Frank Stephenson ranks among the most accomplished living auto designers with a portfolio that includes the revived Mini Cooper, Fiat 500 and the McLaren MP4-12C. How does such a talented man spend his free time? By trolling for fights on an Internet forum.

What do you do with a pile of 15" tires when you have only 18" wheels? You get a bead stretcher of course. This week's troll asks NASIOC for help finding one. We always find 'em near the blinker fluid.

New Viper owner and Viperclub.com forum member "Lanceromance" thought he'd do a little bragging after besting a Corvette in a street race. One problem: it was a lie, the owner's husband does own a Viper and called him out.
