Everyone loves to give someone’s shins a good kick (no? just me then?) but leave it to the English to make it into a sport.

Shin-kicking has been practiced in England since the early 17th century. The sport is easy enough to learn: two competitors hold each other’s collar, and kick out at their opponent’s shins. It’s a game of endurance: the first competitor to cry out “sufficient” loses.
Shin-kicking (also known as hacking) is still played today. There’s a referee and a points system, but given the nature of the sport that part seems kind of pointless to me.
