1. McD.L.T.

Served At: McDonald's
Life Span: 1984-1991

The McD.L.T. is a fabled item for a bunch of reasons. One, the packaging was ludicrous. See, the conceit of the McD.L.T. was that the bifurcated container—two of the old Mickey D's styrofoam containers fused together like conjoined twins—kept your burger (the hot side) hot, and the lettuce and tomato (the cold side) cold. Two, the ad campaign included an appearance from a young Jason Alexander singing and dancing in the name of the hot side and the cold side. Put everything together and you have something so crazy it hurts our hearts to think that we can no longer purchase it. McD.L.T., we weep for you.
