I posted this as a comment to the answer I edited, but I'm hoping to get someone to volunteer here.
The question about Charlie Chaplin entering a look-alike contest and losing has an answer that cites Snopes, and Snopes cites a book and a newspaper article from 1915, with the book using the same newspaper article as its only citation.
Could someone in the US with a library card help us out by getting a copy of this article? You should be able to get a photocopy of the original from the Chicago archives for less than 6 dollars, and they can do this from any public library in the US.
Can any US-based skeptics volunteer to pop down to their local library and help us out?
You'll want a Charlie Chaplin article from the Chicago Herald for July 15, 1915, Vol. 11, RLC. We don't know the headline or page number.
