We owe the celebs a debt of gratitude. Without them, we wouldn't push our bodies to bold new levels of overconsumption. Would we ever eat “healthy fish sticks” if David Beckham didn't tell us to? Would we drink Koffee if Korn didn't drain it from their dreadlocks into our eager mouths? Would we suffer through a single PopChip if Ashton Kutcher didn't goad us to in a horrible racist impression?
