Of 2012's many fails, we have a soft spot for those involving water slides, mudslides, slip n' slides, and... well, you get the idea.One or two from this compilation showed up in our summer roundup of water slide fails, but for the most part it's a fresh batch of bumped noggins, scraped knees, and bruised egos. Suddenly we're not so keen anymore for the return of summer. At least when you wipe out in the wintertime, you have a few extra layers on!
