ecky thump

I offer this not just as a further demonstration of YouTube's spiffy starting-the-clip-halfway-through facility, but also to illustrate the random and unpredictable nature of what makes you wet yourself laughing: the Goodies' Bigfoot episode, from their last-ever series (the one that was on ITV). The full clip is fine, but the bit that did the job was the shot of the Arthur C. Clarke's Mysterious World crystal skull at the end, where it....well, see for yourself. I remember practically wearing out a rental video of this in the mid-80s watching this bit over and over again.
