I almost got married. Yes, I was sober. Cate and I made some joke about it, and there was a Universal Light minister present (other than myself) that offered to do it, and we agreed. This was also while we were handcuffed together with a really nice pair of leather and chain manacles.
Unfortunately, this person got really really trashed and couldn't perform the ceremony. So we didn't. Oh, and worry not, while it would have been publicly recognized, it wouldn't have been legal- because governments have no place sanctioning marriage.
Just an FYI.
