An endless repeated clip of Olive Oyl getting her feet licked by cats...
We've all seen the scene from Shiver Me Timbers, where Olive Oyl is tied up and barefoot, and, after having poured milk on those size 13 soles, the ghosts release two cats to tickle torture her out of her mind. Wikepedia (under the title of "Tickle Torture") shows and endless repeat of the clip in its original Black and White format. Sadly though, there is no sound!
It appears to be an animated .gif image, which, at least as far as I'm aware, doesn't have the capability of including sound.
