Drinking coffee after you go to the dentist.
Here's a fun exercise for a Friday morning...
Go to the dentist. Get a couple of fillings put in (3 to 4 is fine). Nothing like the high-pitched whine of that drill to start your day. Then drive to work (semi-high on anesthetic). At work make yourself a nice cup of coffee. Say “good morning all!” and take a big gulp (keep some paper towels handy).
Warning: Do this all at your own risk.
