A day without laughter is a day wasted
That's a quote from the man himself. I could have cropped tight on the cane and you would still have recognised him. A candidate for London's most famous resident (yes, british NOT american), Charlie Chaplin is commemorated by a statue in Leicester Square. If you don't know about his story, take a moment or two to read up about him - I think you may be surprised.
If you have a moment, YouTube have the last silent film he made, Modern Times, here are the segments: 1 2 3 4 5 6 7. I'm not saying that they aren't dated in places, but he is still funny.
