Originally posted by RioRico The use of an apostrophe to indicate plurality is not uncommon, even in 'mainstream' English. Have you ever seen (and accepted) references to the 60's?
And indeed, some style guides (like the one I grew up with) call for exactly that. According to these guides, the apostrophe is to be used to pluralized numbers ("the 60's"), letters ("mind your p's and q's"), abbreviations ("that guy has a whole bunch of Ph.D.'s") and generally speaking, anything that isn't a real word ("he said nothing but let out a series of hmmm's and grrrr's").
Quote: As for Nacho's, that's because the dish was invented by Ignacio "Nacho" Anaya who served it as Nacho's especiales. Calling it 'nachos' is thus a corruption.
Sheesh, I thought you were kidding, but I looked it up...
And for the record - I'm officially recusing myself from the contest.
