The clever Tui beer marketing campaign has come up with another cunning plan. A video quickly going viral shows a group of mates pranking their friend by rigging up all the water taps in his house to dispense nothing but cold beer.The seven-minute YouTube video depicting Auckland builder Sean Brown, 29, and his buddies carrying out the complex prank has already gathered over one million views in a little over a day, and reports about it were appearing on overseas news websites.While Sean's 31-year-old brother Russell Brown is away at Waiheke Island for the day, Sean and the boys roll some beer barrels under his house, the Tui logo flashing briefly, and they then connect all the taps in the house to the barrels."Basically, idea is we're plumbing his whole house with beer," Sean explains.But that is only the half of it. The pranksters next set up cameras throughout the house. That involves running cables through the ceiling space and even includes a "shoe cam".
