People who wear adverts. It's most obvious in auto racing,
especially NASCAR; nearly every square inch of the driver, car, and crew is
plastered with sponsors' logos. Nearly every pro athlete is a billboard, albeit in subtler ways. Celebrities do it too; the Spice Girls became Pepsi billboards due to the ubiquity of the ads - no need to wear the logo. Hundreds of millions of us wear logos. Posh, Baby, Tiger, and Ronaldo were paid well for it. Were you?
