As I stepped out of my cab and into the SEMA show in Vegas, a booming PA system greeted me with the invocation "Whoa, check out Tiffany -- that's a battery-operated booty!" Sure enough, Tiffany and her cohorts did appear to have battery-operated booties, dominating the tone of the vast area outside the Las Vegas Convention Center. It was all part of the Yahoo! Custom Autos booth where many pierced, tattooed and mouth-breathing young men stared for hours as Tiffany and Co. carried out their pantomine of carnal instincts on a high platform. Clearly, Yahoo! nailed the tuner vibe on its first try. Normally one has to attend a cockfight to enjoy such an atmosphere.
