A great little sketch from The Dave Allen Xmas Special (from 1981, I think), where Allen sends up both Ingmar Bergman's Death figure in The Seventh Seal (thanks to Siggimund for noticing my previous error) and those Public Information Ads that Britain used to produce for TV. Here he plays a chap who has had more than one too many at The Frankland Arms Pub and gets in his car to go home. It's obvious what the warning is, but it has a rather unexpected twist...
