On a corporate do to the South of France we attended a show involving exhausting a young bull. Most walked off in disgust, which our hosts felt was an insult. So they spiked the soft drink punch. No one knew and we drank like fish. The evening descended into mayhem.
I honestly cannot remember much apart from being unable to walk very well, lots of laughing, mad dancing on tables (and a lot of falling off), bumping into things, wandering around in the unlit Camargue. All to the amusement of the sober local gypsy folk.
A friend was stuck in the loo, giggling like an idiot. I couldn't get across to her that as she opened the door, about 30 times, it was her own foot stopping it from opening.
On the coaches back to the hotel one of the girls thought the driver wasn't going to manage the little bridge and jumped up and wrenched the wheel from him just as he was negotiating it ....
The next day, a lot of quiet, hungover people tried to work out what had happened.
