This site doesn't get a lot of traffic (go figure) but I found out today while I was "working on my papers" that at least one resident of the internet found it amusing enough to link to. Check out his post - it has a snarky bumper sticker that I now covet.
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".
