ExDP went to a work colleague's wedding, which was going okay until the reception. The groom and his mates, who by this time were more than a tad inebriated, started loudly regaling the rest of the assembly with their extensive repertoire of filthy rugby songs.
Eventually, the bride's brother decided he'd had enough and decided to put a stop to the singing by the simple expedient of throwing a punch at his new BIL. The whole thing immediately descended into a drunken melee, sountracked by the bride screaming hysterically before running out in tears.
Thankfully, ExDP went to this shortly before he and I became an item so I was spared the pain of witnessing the spectacle
I waitressed at various hotels so attended many a wedding in a professional (ahem) capacity.
At one, myself and the rest of the waiting staff were standing respectfully in a line at the side of the dining room waiting for grace to be said, after which we would leap into action and serve the starter.
The Toastmaster stood up and said that instead of the traditional grace, the bride's father would read out a poem he had written.
A that, the head waiter's lips started twitching uncontrollably, which was bad enough. But after four lines of the poem (which was heartfelt but cringetastically awful )he couldn't handle any more and fled past us and hid behind the screens around the serving area crying with silent laughter. In full view of us, but not the assembled guests.
It was too much for the rest of us and after half a beat, we piled in with him, stuffing our mouths with our aprons to try and prevent any unfortunate guffaws from giving us away.
We only just managed to recover in time to serve the soup safely.
