Absolutely fascinating! This is something i have always wondered about. Can't believe it took me almost 33 years to find out. Great clip!

I wish i would have know about this years ago would have saved me tons of time trying to tickle myself. Oh well live and learn...

Hm - I don't understand. It seems I can tickle myself. No wonder on it

Great site! Lots of interesting info here to tickle your fancy. Thanks!

So, I am actually torturing my four month old?

OK I'm weird

Nice ....
