As Tina Fey recently proclaimed from the drive-thru of a Fatty Fat's Sandwich Ranch, "All of humankind has one thing in common: the sandwich. I believe that all anyone really wants in this life, is to sit in peace and eat a sandwich."

But if there's one thing even more universally rejoiced than sandwiches, it's lunch. There's soup to slurp, chips to crunch, fava beans over mixed greens... it's pretty much a worldwide mouth party. So when Jeff from Improv Everywhere hears that food court piano tinkle and the strings swing in, his love for lunch sweeps him into song; and soon a host of Trump Tower strangers are singing along. Including Ann Curry! Video below.
