Ooops

up side the head.
Our lovely students fill the place with their drunken cheer. They're enticed in with all sorts of cheap drink related frivolity. One historic favourite was the tequila line. The DJ would wait until the dancers were flagging a little and the bars were lulled before they all switched to water.
He would summon the dj's assistant to get the two tequila bottles with speedpours. The oops up side you head tune gets on the PA and the floor fills with lines of drunken fools sitting in rows with their backs between each others spread legs. The rows would lean forward in sync, touch the floor on one side, touch the floor on the other then take both hands to their heads and lean back. This bizarre seated synchronised wiggling to a tune of little merit only survives on the promise of strong booze. The dj's assistant works his way up and down the lines pouring tequila straight into willing mouths. Not a great deal but enough to help and get them moving - perhaps back to the bar after they've worked their way up off the floor.
This had become a time honoured tradition, which in night club terms means it had lasted longer than 1 year. The best results we had from this were those so distracted by the slim, shifting line of tequila and their attempts to get their mouths under every last drop that they lean forward as the line they're sitting in reaches the end of their backstroke. The result, clashes of heads, spitting of tequila into hair and eyes of relative strangers and general hilarity for all those standing watching. Even the sober, bored looking ones sweating in a tie and jacket.
