Occasionally you may see guys with cars and trucks with unneeded spoilers, mudflaps, exhaust extensions, etc. And occasionally you might hear about people who do things for luck during sports games.
Many of us may find all those things to be stupid. But I'll bet that guy with the lifted truck likes his truck a whole lot more than you like your car. And the people who wear lucky socks while watching football enjoy watching more than those of us that think those things are dumb.
Maybe they're not so stupid after all; they're having more fun.
(Those plastic balls hung under trucks are still embarrassing. If your truck lacks balls, then spend your money on real ones, not fake ones.)
