I wasn't even looking for this one. Going to Fark as I usually do, I happened upon a news story at Little Green Footballs that is really interesting.

The story cites a post at Free Republic which suggests that some National Guard records supplied by the Bush Administration are forgeries. As the post notes, the Bush records' age is questionable, since "every single one of these memos to file is in a proportionally spaced font, probably Palatino or Times New Roman. In 1972 people used typewriters for this sort of thing, and typewriters used monospaced fonts." For an excellent look at this, see the Aug. 18, 1973 memo, which contains a proportionally spaced font, "smart quotes," and a superscript "th." Only modern word-processing software is capable of producing superscripts like that and smart quotes (quotes which curl in a particular direction, depending on whether or not they're before or after a word, instead of being just straight lines). The post notes:

The use of proportionally spaced fonts did not come into common use for office memos until the introduction of laser printers, word processing software, and personal computers. They were not widespread until the mid to late 90's. Before then, you needed typesetting equipment, and that wasn't used for personal memos to file. Even the Wang systems that were dominant in the mid 80's used monospaced fonts.

It looks like someone used Microsoft Word to type these documents, then ran them through a copy machine several times to make them look old. But what the forger forgot to do was turn off such AutoFormat options as superscripts and smart quotes! This evidence is damning and cannot be ignored. Look at other, verified Bush records: all in a monospace font (they're available online, I don't have links to them at the moment).

Does this definitively spell out f-a-k-e? Perhaps not, but it does, as one commenter at Little Green Footballs noted, it raises the BS Detector.
