Mitchell Fairbarn says he drank between 30 and 40 beers on the night that he stole a flamingo from a Vegas resort

That seems like it'd get you into potentially life-threatening territory.

EDIT:

Says that 40 beers would be maybe a BAC of about 1.08%.

https://en.wikipedia.org/wiki/Blood_alcohol_content

This says that a BAC of 0.4% is "Potentially fatal, may result in a coma or respiratory failure".

EDIT2: It doesn't say how long the period was that he drank them over, but going off the BAC calculator above, it wouldn't make that much difference, as it looks like the decline is linear, and there just couldn't have been enough hours to dramatically reduce it.
