It would take 28 bottles of Shiner Bock to kill me
The death threshold corresponds to a three-hour drinking period. I think their calculations may be a bit off on some beers, though — it said it would take 13 Sierra Nevada Bigfoots to kill me. As strong as Bigfoot is, I can guarantee you I'd be unconscious long before I ever got to 13. Perhaps if someone forced the rest down my throat. Hell, just two of those will send me down for a nap.
EDIT: Dammit, within just a couple of hours of posting this, the link no longer seems to work.
