Oh, God, this is the most hilarious Tony/Steve interaction fic I've ever read! I've read plenty, but it's mostly about their "(b)romance" and how much they utterly and completely adore one another. This telling is a lot funnier, although there can be comedy in people snarking about Tony/Steve being an old married couple. But still, funny! And Thor's line to Sharon is just an awesome pick-up line.
