An often overlooked perk at Burger King is its penchant for handing out low-budget jewelry. I'm talking about the venerable old Burger King cardboard crown, free to any student who has the courage to ask. Aside from its obvious function as a classy piece of headgear, Burger King's crown also serves as a great sweatband. I jogged around Green Lake wearing one of these. Passersby filled my world with smiles.

Stick with Burger King's traditional gold-and-red crown, the one with the Burger King logo tastefully emblazoned across its faux-foil surface. That's class. You're the King, now!
It obviously sounds like a truth or dare kind of thing.
