It's Friday. Why not play a prank on your hard working web designer and use Comic Sans It! to mess up his pretty website, just drag the bookmarklet to your browsers bar and any site can be comic sansed, causing panic attacks if you bring it to the designers attention with a straight face: "When I look at the site on my computer... it's all in comic sans, see?"

If you do that though, you must repent. You've been bad. The designer will type your name into Comic Sans Criminal and shame you publically. After that, hit the pub and make up.
