With weather having taken a turn toward the frosty, we might be done with ice creampocalypses for a while. But not to worry, Z Burger in Tenleytown is picking up the free-food-as-marketing-tool slack with a free burger event today. Via NBC4, show up at the store’s Wisconsin Avenue location with a coupon that can be found in City Paper and get one of Z Burger’s classics for no more than the effort it took you to get there. Maybe pair it with some of their signature peanut oil-fried fries, or a milkshake. If you can’t get your hands on that coupon, rumor has it you can partake of the offer by just uttering the “secret” code word. Hint: the word is Foxxy Cleopatra’s mantra from Austin Powers III, and rhymes with the title of Shaq’s silver screen debut.
