A colleague from Tokyo dropped off a green Kit Kat for me this morning, but with a shit-eating-grin on his face; I looked at the color and said "it's wasabi, right?" He was disappointed that his surprised was ruined.
Nearly every friend I have from Japan has tried to get me to eat a spoonful of wasabi while at a restaurant with the "it tastes like candy" line. Come on, I don't lead a completely sheltered life. I like wasabi, by the way.
