Calgary hockey streaker
Dumbest streaker ever. "Streakers aren't necessarily all that uncommon, but people who knock themselves out on the ice in front of thousands of people at a hockey game, yeah, that's a little more rare." He recovered consciousness in time to wave the "duuuuuude" sign as paramedics wheeled him off the ice. More.
UPDATE: Another great photo of the streaker climbing over the glass.
