Print something mysterious on the printer at work. Let the printout sit there, so someone else discovers it. It’s fun to make aliens come out of the printer. Here’s what my alien said:
GREETINGS
EARTHLINGS.
THE HP LASERJET 4200
IS ACTUALLY AN ALIEN SPY
HERE TO TAKE OVER YOUR PLANET
JUST THOUGHT I’D LET YOU KNOW
HAVE A GOOD DAY.
You can download this file as a pdf. Print and let the takeover ensue.

HA! I love it! Unfortunately [or fortunatley”> there are very few common area printers, most teams have their own and I, in my role, have my own. I wonder if I could confuse myself by printing one of these and leaving it on my printer for … well, … who knows how long, only to discover it later?
