What I love about that is if you put the quotation marks around what Mr. Shoe Shine is allegedly saying, this sign would be totally grammatical. As it is, I guess Mr. Shoe Shine doesn't generally say things or something. Thanks, Noah who posts at Skull a day.
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".
