On October 17th in 2002, 21 year old Lethbridge College student Timmy Hurlburt flubbed an attempt to streak the Saddledome surface with five minutes remaining in a Boston Bruins/Calgary Flames matchup.
Acting on a $200 dare, Hurlburt successfully scaled the nine foot glass clad solely in red socks and a wrist-watch only to botch the descent. Landing off-balance, Hurlburt's head struck the ice rendering his untanned naked mass unconscious and in plain view for all to see during the ensuing six minute delay.
Hurlburt signaled his return to consciousness with a pair of hand-gestured horns whilst exiting the rink secured to a stretcher to the rousing approval of onlookers and his born-again Christian mother's chagrin. The game ended in a 3-3 overtime draw. Timmy was released from the hospital the next day.
That's today in NHL history.
