If watching others fall down is hilarious in and of itself, that means watching people fall down stairs is double the fun.

The above video, which has compiled over three minutes of people taking horrid yet hysterical tumbles down stairways, was given to us by YouTube's own WWideInterweb -- the same user who has provided other FAIL compilations such as Ultimate Dodgeball FAILs, Ultimate Segway FAILs and Ultimate Ladder FAILs. (Basically he's the Ken Burns of fail videos.) And while they've all offered us tons of laughs (and occasional cringes), this one might be our favorite.

Which person do you think failed the most in this video? Our vote goes for the last guy... ouch.
