having recently acquired cable, I know that the "food" "network" is really a network, and every time I turn it on there's actual food. Maybe it's staged for tv. Actually, I think this sign, found by colby on 3rd avenue in NY, is working under the assumption that tv networks get quotation marks, and then quoted both because vertical quotation marks look weird no matter what you do. They don't, though.
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".
