Haha, those commercials were pretty rampant back when I actually watched TV, and my mom and I are both really ticklish, and my dad likes to poke us, and he thinks we're crazy because we both do the little Pillsbury Boy squeaking thing when poked.
While I do poke a lot of people, I personally get rather upset when someone else tries to do the same for me -- I've bitten my tongue and hurt myself in other ways.
