I imagine that these quotation marks are to indicate that the driver is a person who wouldn't normally use an expression so foul as "shit" but in this case, for a fancy airbrushed car decor, they are making an exception. Thanks, Bren.
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".
