The submitter does not know why these dentists have assumed pseudonyms, and neither do I, nor why their pseudonyms are so common. I'd go with something awesome if I was going to pick a dentist name, like Dr. Awesome.
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".
