So beer has been brewed for roughly 5k years... I wonder how long after it was invented there was some variation of
"You think that's hard? Hold my beer..."
5k? Much older than that. Pottery that is around 13k years old has been found with beer residue, and since it was occasionally brewed in stumps and the like it's very probably older than that. Hell, there's rules and procedures about beer in the Code of Hammurabi, as well various other places (up to and including prayers).
As for "Hold my beer", I suspect some variation was grunted out by the very first hominid who discovered inebriation. Wouldn't surprise me if most mammoth hunting parties and the like got ritually buzzed beforehand. (You know, so as to face down a multiton animal using only a burnt stick.)
