Not sure whether this is the kind of funny you're looking for: 'I touch myself'by JS & AAR - or the 'Buffy pop up vid'. It's timely, with Buffy's anniversary, but it's also old, so quality is not as sharp as we come to expect nowadays. Also not sure whether people still remember the M-TV pop up videos?? But this was the first vid I ever saw (at a con) and which got me into vidding.
