Tired of reading all of those racist, anti-Semitic, gross, nasty, hateful, and just plain dirt-dumb stupid comments on YouTube? Now you can make everyone as smart as a rocket scientist, or at least as smart as a Nobel Prize-winning physicist (and prankster, juggler, painter, bongo player, and lock-picker), namely Richard Feynman.

FeynTube is a Greasemonkey script that replaces all YouTube comments when quotes from Feynman. You can switch off FeynTube simply by switching off the Greasemonkey icon at the bottom of your browser.

The FeynTube page describes how to install both Greasemonkey and the FeynTube script. [Thanks, Blake!]
