Sadly I can't find the Alas Smith and Jones head-to-head crime detection sketch, part of which went something like this...
Mel: They eventually identified the culprit from his gait.
Griff (pauses and frowns): You mean he left his fingerprints on it?
Nor did Jasper Carrott - he thought it was a model of that well-known car manufacturer 'Robin' :lolol:
That's the sort of thing Delboy himself might have uttered!
