Show HN: Rick Roller, a Chrome Extension to rick roll coworkers

Hey HN, Rick Roller is a Chrome Extension that will randomly rick roll the user.

I wanted to pull a fun and harmless prank on some of the officemates who are always leaving their computers unlocked when they leave their desk, especially for April Fools' Day. So I put together a quick extension for Rick Rolling them :) The results have been pretty great so far. Hope you like it!
