put wget -O- -q https://gist.githubusercontent.com/snipe/5512408/raw/db9f4051eeb1079de436ec5ae9ba9aff2a99549c/gistfile1.txt in an unsuspecting colleague's .bashrc when they leave their workstation unlocked :^)

Niceeee

Oh man, my comment is over five years old. I've grown up in the meantime and want to apologise for the immature suggestion of pasting this code into someone else's terminal.

Of course you should instead put wget -O- -q https://gist.githubusercontent.com/snipe/5512408/raw/db9f4051eeb1079de436ec5ae9ba9aff2a99549c/gistfile1.txt into the .bashrc or .zshrc of your coworkers.
