The earliest reference to the Old Librarian's Almanack is found In 1907, when the novelist Edmund Lester Pearson mentioned it in his Boston Evening Transcript column. It was, he said, a small almanac from 1773 that contained the "opinion and counsel" of a curmudgeonly librarian whose ideas were strikingly non-modern. Two years later, Pearson arranged for the reprinting of the Almanack, and it was favorably reviewed by many newspapers which accepted it as an authentic 18th-Century curiosity. Very few people realized that there was no Old Librarian. Pearson himself had written the Almanack as a joke.

Someone who falsely claims to have played an Oompa Loompa in the 1971 movie Willy Wonka and the Chocolate Factory. There were ten actors who performed as Oompa Loompas, and pretending to have been one of them is a way for a person of short stature to gain instant celebrity status. It's an easy lie to get away with since very few people know who any of the original Oompa Loompas were. So over the years there have been a number of cases of this deception. For example, in 2005 a Nevada man, Ezzy Dame, was exposed after having passed himself off as an Oompa Loompa for over 20 years. More info: BBC News
