If you've never seen this show, or experienced David Jason's particular brand of genius, the scene of Del-boy falling into the gap left by the bar flap may not sound like a candidate for funniest moment in British Comedy. However, it's all in the execution. Falling-over gags are, of course, as old as the hills, but this one really takes the cake. Del falls through the bar in one clean motion, without bending his body even slightly. As he disappears out of view, he is at well under a 45 degree angle with the floor. It really has to be seen to be believed.
