Last week, we were so excited to see Bam Margera join the Nitro Circus that we forgot dude was busy getting really, really, ridiculously old! Bam celebrated the big 3-0 on Monday, and as he moves into his third decade of life, our friends at Jackassworld.com decided to take a look back at some of the stupider funnier things he's done over the years. Enjoy the stroll down memory lane (better to look back than ponder his future of senility), then tune in tomorrow night at 10pm for an all new Nitro!

Oh, it's so on. Jackass alumnus and Viva La Bam star Bam Margera once reigned as king of immature pranks, parental abuse and eccentric house decoration, and while it's been eons since we've seen or heard from the crazy mo fo, the Nitro Circus crew whom he inspired is getting back in touch.

Come tonight at 10pm, the boys will head to the Land of Bam a.k.a. Amish Country, where they'll race dirt bikes through the pro-skateboarder's garden and perform some freestyle motocross on his garage roof. Don't miss the show, and in the meantime, refresh your memory of the NC guest's trouble-making ways by checking out the first season premiere of Viva La Bam!

There's a reason Nitro Circus comes with a "Don't try this at home" warning: the stunts are dangerous, dumb and borderline illegal. They're also funny as hell to watch. And this week's roster of stupid human tricks had us glued to our seats in a this-is-awesome-but-I'm-glad-it's-not-me sorta way. So which stupid stunt was the all-time craziest? Take our poll and let us know!

Both Bam Margera and Ryan Sheckler have proven they've got the moves -- but in the end, only one can go down as the best skater in MTV reality show history. So who's wheelin' and dealin' and who's still learning how to rock n' roll? Watch this video showcasing the stars' gnarliest tricks then let us know which skaterboy is your all-time fave!
