It's funny the things that stick in ones head. Back in the '90's, I think, there was some movie about the grunge scene in Seattle, I think, but what I do remember is the leading character was looking for love and, hopes dwindling, decided someone who'd say "bless you" when she sneezed might have promise as a potential partner. The last scene, I think, was her sneezing in an elevator and the grunge dude who'd looked less likely than the clean cut guy says "gesundheit" and we, the audience, are left to think that maybe he was the one. Matt Dillon was the grunge dude. I think.
Ok, some of the details are sketchy and didn't stick, but the "bless you" part comes into my head every time someone in the office sneezes and I say "bless you."
