First I'd have to go back to when I was younger and ticklish. I remember once back then where I was laying on my back with no shirt on and I very lightly ran a finger around my armpit. I could only do it for a few seconds because it tickled too much! And as a kid, I never went barefoot! I guess I was just afraid of them being tickled! So, if I were to clone me and have my way with my younger, ticklish me, I'd tie me face up, spread eagle, and tickle my feet and pits mostly, though my sides were pretty ticklish too! 😛
