Everybody has grand, dumb ideas when they're drunk, but it takes a dedicated pair of drunks to actually follow through on one. Hats off to David Copley and Eric Johnson, owners of the Auld Dubliner Irish Pub in Tustin, Calif., who did just that by filling an 8-foot-tall glass with 430 gallons of Guinness stout recently.

A crowd of 400 people gathered in the bar's patio to watch the mammoth 900-lb. glass, made of shatter-resistant acrylic, being filled with 2,772 lbs. of beer. Though it has yet to be certified, the feat should earn the bar a place in the Guinness Book of World Records for world's largest glass of beer.

The previous record was set Harry Caray's Italian Steakhouse in Chicago, which filled a tiny 4-foot-tall glass with a measly 1,000 lbs. of beer in 2008.

The Auld Dubliner glass will be on display through January of next year, but the beer won't last that long. "We dipped our glasses in and we have a pump," co-owner Johnson said. "We're going to drink it."

Look for Eric Johnson to set a new record for world's longest continuous urine stream later this week.
