Ryan Dunn made a lot of people laugh with all of the crazy stunts he did on 'Jackass' and its various spin-off shows for MTV. So the network, along with his friends, family and castmates, presented 'A Tribute to Ryan Dunn' (Mon., 10:30PM ET on MTV), featuring a look at his life and rise to fame, as well as never-before-seen stunts.

There was also a cautionary element to the story; Dunn died in a drunk driving incident. Had he not been drinking, he'd likely be alive today, and that wasn't lost on Johnny Knoxville in his remembrance. But mostly, his friends and loved ones were joyful that he was happy with his love and his life, even if it did come to an end far too soon.

Yet another new reality series coming to MTV. This time, it's all about the life and times of pro skateboarder Rob Dyrdek and his "bodyguard/best friend/roommate" Christopher "Big Black" Boykin. Dyrdek has been a pro skater since he was 16 (he's now 31). He hired his bodyguard when Dyrdek kept getting harassed by cops for skating in the streets. MTV cameras will follow the two around in the home they share in the Hollywood Hills and out on the skateboarding circuit. Dyrdek describes life with Boykin as "all day comedy".
