Yearbook typos are funny (and I say this as a former yearbook editor who died a little inside each time she found a typo in her finished project, so actually by "funny" I mean "AAAAAAAAA!"), but check out the comment from the yearbook company at the end of this article about spellcheck turning evil. Dude, if it's happening EVERY YEAR, maybe at some point you want to work out a way of fixing the system? Maybe, call me crazy, but perhaps DISABLING FREAKING SPELLCHECK?
(Also, could someone open up Blogger's spellcheck and add the word "spellcheck?" Kthxbai. And add "kthxbai" while you're in there.)
