I'd never heard of 'Gurning', a sport that allegedly originated in the Middle Ages.
It is said that townspeople would throw a horse collar on the dubbed, 'Village Idiot', who would make ugly faces in exchange for ale. (...and now you know!)
Slap a collar on and call me, 'Sporty'! (My scraf...I call it a scraf rather than scarf...will have to suffice.)
Video explaining this odd activity is below.
