Know any hilarious youtube videos?

Comparable to "Tricycle Wrecks" a href="http://www.youtube.com/watch?v=1reby_6_oco" rel="nofollow"http://www.youtube.com/watch?v=1reby_6_o…/a Worthy of showing each to like 20 of my closest friends and having us all laugh hysterically. Please leave a link to each video and the title of each for quick reference. Thank you!
