Reprimands from fourteen years or so as a sysadmin:

1. Annoy-a-trons are not appropriate at work and should not be placed in supervisor's office, causing him to dismantle everything electronic in his office. It's not funny the second or third time, either.

38. Hiring PHP developers does not contribute to the quota of employees with disabilities.

57. RJ-45 ends are not "network seeds" and should not be scattered under floor tiles in an effort to cultivate a server farm.
