Hopper

Yesterday was As Seen's 200th blip and in it he used conkers to display the 200....this posed the question ,why are they so called? Apparently it originates from a game called "conquerors"....originally played with snail shells and then hazelnuts ....now Horse Chestnuts which are now conkers (conquer)...That poses the question of my blip today .....which leg does a grasshopper hop on?
