Foot tickling, and laughter

[magic fingers]

Does anybody have any true stories about your favorite foot ticklee. By favorite, I mean someone who breaks out into pure laughter, when their foot/feet are tickled? My theory is that ticklees laugh more when their midsection is attacked, because laughter comes from the stomach. However, I've known a few ladies who, if you tickle their feet, they laugh, heartily, and helplessly, and it is so adorable! I'll share a story or two, but right now, I'm pressed for time, so I'd just like to hear about your favorite foot ticklee, female, or male.
