Never again might you see a group of men so excited to knock nuts.

Conkers is the name of a British children’s game involving chestnuts (also called conkers) threaded to strings. Holding their strings, players thwack each other’s nuts until one of them breaks or is knocked to the ground. The game became popular during the 20th century and remains in vogue today, though chiefly among menfolk. 

This handy video lays out the four key steps to conkering the sport. It also explains the scoring system and rulebook, so prospective competitors in the National Conker Championship—pay heed. If you want to make sure you’ve got the toughest nuts, then consider filling your conker with glue, letting it dry out in the dark for a year, or passing it through the belly of a pig.

May the best nuts win.
