Eight....
Hours????

That's not even a contest, imo--but maybe I'm just used to associating with professionals 'round hyere. Go with a light beer--thinking pilsner though I might be biased because the way I drink 'em like water they go down real easy for me. I can easily down that amount during a good party, and frequently do so on a weekend day if I'm outside mowing or bonfire or such.
Only time I ever had a beer drinking contest was years ago with a friend of mine, in a local Chapel Hill bar. We decided to have a competition to see who could drink a large size (64oz?) pitcher fastest--and it had to be done inside 5 minutes. Loser pays. So we took a booth and ordered two without glasses for practice. Neither of us beat the 5 minute mark but both were done before 6. We ordered another couple pitchers and went after it. I won; he finished his at about the 5:10 mark.
Then we ordered a third pair of pitchers to celebrate, and pretty much nursed tnem over tne next 30-45 minutes! Weren't there much more than an hour.
Maybe that's the ticket--shoot 'em down before you realize you're smashed, and have a designated driver.
