Useless trivia time.
If you have access to an episode of Granada TV's "Adventures of Sherlock
Holmes" check the title sequence at the moment that the three street
urchins oooh and aaah over a piece of glassware in a shop, from outside
the window, only to be sent off by a constable of the law, but not
before they can all stick out their tongues.
The urchin on the right (and the first to run) appears to be the young
David Schneider. Apparently he didn't get that unique face in adulthood.
