Discontinued Olympic events of years past. What I would do to see Dueling Pistols in action...
Behold: The Korbut Flip.
Named after Soviet gymnast Olga Korbut, the Korbut Flip involves standing on the high bar and performing a backflip, then regrasping the bar on the descent. The move was banned because it interrupts the rhythm created by swinging, but also because it's CRAZY DANGEROUS.
Warning: This video contains awesome, dangerous, and insanely badass gymnastics moves.
