Before I left for Alberta, a coworker of mine showed me his homemade nunchucks.
He's an older guy.
He hides his nunchucks in two different socks in his truck--completely legal--he assured me.
Amused, I asked him to show me "a thing or two with the 'chucks".
On his third underarm pass, he hit me in the elbow so hard it made my left arm go completely numb. The numbness lasted for over an hour. That ended the fun as quickly as it had began. He apologised and hid the nunchucks like some pre-teen stashing porn.
He has sais, but I decided it would be better that I not ask for a demonstration. I prefer blunt force trauma to sucking wounds.
