I kid you not! "A suited protester from the Occupy London Stock Exchange holds a placard stating 'Time's Up!' whilst business people walk by as they continue their demonstration that started on Saturday outside St Paul's Cathedral, near the London Stock Exchange in London, Monday, Oct. 17, 2011." This was in the notes to photo 6 of 63 from "Occupy Wall Street: Images from the Front Lines", Yahoo Finance!, 2011-10-17.
I read this as "business people are demonstrating as they walk by." "Business people" is the first plural subject in the above paragraph.
I guess I can't complain too much. Today I found a "the the" in a blog entry I wrote five years ago.
