I was on MLIA and I was reading a story about someone typing in "what would happen if I hired two private investigators to follow each other" to Google and hitting "I'm feeling lucky" so I did it.
I got this:
http://www.reddit.com/r/AskReddit/comments/9g8cr/what_would_happen_if_i_hired_two_private/ If you scroll down a little, there's a joke:
"The solution is obvious:
They'll stay within an area of known radius.
Because of course:
The PI are squared."
The user? tomparker. Yeah...I had an old math teacher with that name. It's more than likely a coincidence but the fact that it's a math joke was just hilarious. It's his humor too XD
