I can’t imagine how much he drank in 4 days. The last time I was to Wales, I managed 5 pints on a pub crawl. I was maybe 130lbs at the time, so that was an impressive amount of grog for a small guy like me.
That’s nothing for a “pro drinker”.
Try a 750 of Jack and a six pack.
-This is not recommended, nor should it ever be done in public
Back in the day - mainly muscular Irish and 233 lbs.
