I've been to plenty of weddings over the years, many of which shotgun. Most of them are indistinguishable, as they all seem to follow the same general pattern. "Do you take this man, sickness and health, love and cherish, until death or financial trouble..." "Do you take this woman, sickness and health again, honor and obey, until something better walks along..."
The ceremony usually lasts a little too long and during the 30 minutes or so in which I can't talk or distract myself I am stuck in a folding chair examining my darkest inner-most thoughts. I look around and catch a tearful look on the bride's mom's face and I start to well up. But then I see the groom's nephew playing with his iPhone and my thoughts turn violent as I reach down and grab a nice, round river rock. I check out the bridesmaids and wonder why they avoid my efforts to establish intense eye contact. "The sun must be in their eyes" I think to myself.

After the ceremony I grab a plate of food and smuggle it out to the parking lot and eat in my car, so as to avoid eating with strangers and the awkward conversation that follows. I then take a few hits off the flask, dump some altoids in my mouth, and walk confidently back into the reception area, where I am met with an air of celebration, and people desperately trying to find segues for leaving.
I dance with a drink in my hand because I think it looks cool, and I loosen my tie for the same reason. In between slow dances I play the "mother-daughter" game in which I stare at a girl until her mother notices.
After the reception I go home by myself and leaf through the wedding magazines I keep in the bathroom as a single tear rolls down my face.
