I.M. So Glad We Had This Time Together

Much as Carol Burnett used to secretly give a "shout out" to her grandmother by tugging on her ear, Iron Man likes to acknowledge various bystanders he's bedded with a similar gesture. Many a lass (and lad!) has spotted Iron Man weaving tipsily through the troposphere and wondered, "Does he recall that glorious night we spent in (Palm Springs/Omaha/the Motel 6/that abandoned rendering plant/a fugue state)?" And then they see Iron Man giving the "signal" (even as his metal faceplate remains infuriatingly sphinx-like). Their spirits soar, the sun seems to shine a little more brightly, and their day seems suddenly rich with promise. With beaming smiles, they return the signal... and then they see (on average) eight other people, from all walks of life, smiling up at Iron Man and doing the exact same thing.
