🙂 Well… 😆 The strange wobbly effect wouldn’t naturally be introduced during the gif compression, so it must either be due to the specific way in which an automated gif-making site was taking parts of the image from different times during the frame-rate conversion (or something similar), or it was in the source material before the gif conversion.
It almost looks like the ‘rolling shutter’ jelly wobble effect you get when recording on cheap video cameras – i.e. when the camera records the horizontal lines so slowly that the scene has changed by the time it gets to the bottom.
I like the mountain head smash on the wall scene for the bit of head that falls off the wall at the end. It’s the little touches that makes my arse really knit buttons.
