say you cracked open a budweiser and left it sitting on the counter for days until the carbonation died out...

can you bring the now flat budweiser back to life by re-carbonating it?

You could try peeing in it. That might actually improve the taste

Seriously though, I don't know if you could recarb a single bottle or not. The big breweries run their stuff through some very fine filters so you're almost assured that there is no yeast remaining in it. You'd almost have to pitch a nano sized wort and quite honestly it's probably not worth it when the stuff is what, $.80 per bottle?

Plus, it would be oxidized and stale. If you had a keg of flat beer, you could force carbonate though.
