DO NOT BE ALARMED! PUBLIC SERVICE ANNOUNCEMENT!

If you see something, say something.

If you see someone do something somewhere, say something to someone somehow.

If you see someone do anything anywhere to something, say anything about something to anyone somehow, before something happens to someone.

If someone sees anyone saying anything somewhere that is somewhat suspicious, say something-or-other to someone-or-other in someplace-or-other to prevent someone doing something everywhere sometime-or-other. 

If anyone everywhere ever does anything anytime to anyone everywhere else, say anything to someone somehow to prevent everything happening everywhere forever. 

REMEMBER: STOP ANYTHING HAPPENING EVERYWHERE EVER, BEFORE IT'S TOO LATE. 

The Department of Existential Security

Note: Oh, and this: be alert but not alarmed. Definitely do not be alarmed. Do not be alarmed about being alarmed either, merely remain alert to signs of alarm, rather than being alarmed at your alertness. By being alert to the alarming possibility of alarm about your alertness, you will avoid this alarming alarm about something done by everyone anywhere somehow.
