One of our absolute all-time favorite Onion articles was this hilarious piece about an ill-conceived McDonald’s mascot named the Hammurderer, who killed the restaurant’s other mascots and stole their burgers to satisfy his cravings. Certainly no real restaurant promotion has ever failed so disastrously, but several featured in mental_floss’s listicle of 7 Food Promotions Gone Horribly Wrong come surprisingly close. We’re going to stick with McDonald’s for the prize on this one, whose Norwegian chains came out with a brilliant new sandwich in 2002 called the McAfrika, seen at right. Brilliant (and gross).
