Marnie linked me to this website (a sample image above). It really is one of the crazier things I have ever seen, I don't know if I can take it as satire, because what exactly is it satirizing? Regardless, there is a strange use of punctuation, to be sure.
I don't usually post the following: newspaper headlines, personal email, craigslist postings, unprofessional websites. I also tend to not crosspost things from other blogs, since I have so much unique material waiting for me to get to it.
Things I see a lot: silica gel "do not eat"; hair dryer labels; inside the bus "do not drill"; Wal-mart sign about IDs; coffee machine with "2" cup sizes; employees must "wash hands".
