Submitter Tyler tells us these signs are from a pet-themed trinket store. These must be some pretty sweet trinkets, since you can't mime photographing them, and they are only fake polite about keeping your kid's dirty mits off.
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".
