You don't need a PHD in marketing or sociology to realize that drinking and sports are BFFs. That said, here's a Happy Hour factoid to file in the "things that don't surprise anyone at all" category: 1 in 12 fans are legally drunk when leaving MLB and NFL games. According to a recent -- and painfully obvious -- AP story, "Alcohol is as big a part of going to a baseball game as peanuts and Cracker Jacks." In other news, birds can fly, water is wet, and Lady Gaga looks like a man. Moneyshot pullquote below, via the AP:

At the University of Minnesota, researchers became interested in the topic of drunkenness at games after seeing a steady stream of small news items involving assaults, car accidents and rowdy behavior by drunken fans. Among the findings from the school's studies since 2005:

Alcohol laws and guidelines at stadiums are poorly enforced: Researchers said 74 percent of people pretending to be drunk were served and they were three times more likely to buy it from a vendor working the stands than a concession booth.

Thousands of fans leaving games and getting into their cars are drunk: Researchers took breathalyzer tests of 362 fans at 13 baseball and three NFL games and found 8 percent of them — 1 in 12 — were legally drunk, while 40 percent of them had at least something to drink. That 8 percent, when multiplied by the thosands of people attending games nationwide, leads to a staggering number.
