Hey man,
Hell yeah, the cartoon tickle / tickle torture scene things are basically some of my earliest memories regarding me liking tickling. It was that April O'Neil clip that got me too, though that Gummi Bears one is there too! Oh, and there was one in Mario Brothers ages ago - think it was Luigi getting tickled. Shame it wasn't Princess Toadstool!
It did make me feel uncomfortable though, if anyone else was watching it at the same time. Haha, kinda like when someone's on telly humping away giving it "oooh, aaaah" and your mother is there...
