That is without a doubt the most torturous tickle scene in all of mainstream video. I remember seeing it as a kid and being totally floored. Of course, it would have been better if the Stooges had turned the tables on their captors. In fact I used to fantasize about doing a role-reversal remake of that short with three cute babes instead of the Stooges... and the tickle-torture scene expanded to about five times the length, of course.
Hey, how about the girls from Friends... Monica as Moe, Rachael as Larry, and Phoebe as Curly??? Works for me!
