In my
Fireworks Lois and Clark meet waiting in line at Disney World. And in
Green-Eyed Monster they meet at a bookstore. The cast of characters is the same but they've been regulated to working at the bookstore.
I like
Stardust by Caroline K., where they meet in a bar.
Terry Leatherwood often uses alt-beginnings for his stories. "Play some Mountain Music" and "The Circle Squared" are two excellent ones that come to mind.
