When I yawn I get these random after-tastes (they never have anything to do with recently eaten foods, in fact they're not even always foods at all). pretty wierd. Currently it's rye bread - like the ghosts of rye breads past coming back to haunt my throat, mwahaha! =) Chocolate yawns are pretty good. But sometimes it's stuff like sharpie marker, or clean laundry, or pine. I'd actually have to say the laundry one is my favorite - always makes me feel warm and fuzzy. yeah, I know I'm strange. heh.
do you have flavored yawns???
