That's 25 quarts (6.25 GALLONS) of coffee in one day (assuming an 8 ounce cup of coffee). I'm not sure if it's even physically possible to drink that much coffee in a day.
Yes, it was to point out that it is not possible to drink 100 cups of coffee in a day but it is entertaining nonethless.
However, some drinking world records are beyond the realm of health and sanity:
"As the plane arrived in London, Walters raised his 44th can to his lips and drained it as thought it were his fourth. From all accounts, he wasn’t in bad shape. not if you consider he’d had 44 beers at high altitude and a couple of unofficial palate cleansers during the stopovers. He was all right just says O’Keeffe. He was lighting cigarettes filter-first. I guess that’s all right. You can do that sober."
Ok, I'll try. 8*D
