Cool stories. I will relate mine from my wedding 4.5 years ago.
Since my wife and I were both older (well, at least I was) and I already had a house and everything I needed for it we just asked our good friends (who a lot of them are homebrewers) to brew us their best beer for a wedding gift. My wife's task was to find a reception hall that would let us bring our own beer and not charge us. She did a wondeful job of finding a place and we had a wonderful reception/party.
The final results were that we served 12 different homebrewed beers on tap (I brewed 2 of them) from CAP to Impy IPA to Old Ale (with cool names like Old Ball and Chain, Hen Pecked Hefe, Pre-Nup Pilsner, etc), our toast was with champagne-style carbonated mead (a bottle on each table), and most of the guests received a bottle of Wedding Wee Heavy that I brewed as favors. I also had glasses made (brandy snifter type) with my brewery logo on one side and the wedding date and info on the other and gave those as groomsmen's gifts so they could drink out of them at the party.
It was a wonderful evening that I remember fondly. Oh, and several of the beers went on to win medals for their brewers, including 1 best of show and 1 medal at the NHC.
