You've been a sysadmin too long when...
…while walking to the restroom in search of relief, you:
- spot a printer with a paper jam,
- fix the jam,
- wait to see if it's fixed,
- clear the second jam,
- diagnose the problem,
- solve the problem,
- reload the paper tray,
- verify that it's printing correctly.
Then you resume your trip to the restroom.
