What are your top three ticklish spots?

For those who are brave enough to expose their weaknesses, list your top three ticklish spots, with a short description. I'll be the first human sacri... err, volunteer.

1) Feet - always been sensitive here, even vicious and sadistic siblings didn't desensitise me. It's funny that I do go barefoot a lot and they're not too soft, yet someone tickling me there still makes me squirm and laugh.

2) Belly - last time I was tickled here, the tickler remarked that it was very funny watching the muscles instinctively twitch and wobble, as well as my squirming torso.

3) Sides - ever had a very ticklish spot that doesn't necessarily make you laugh heavily, but make you squirm a metric fuckton? Well, those are my sides when you quickly wriggle your fingers across them. It feels good yet agonising at the same time.
