Whenever I want to procrastinate, I use these sites: - This website has demotivational posters that are added daily. Quite a few of them are hilarious. - This site has a daily comic that I like to read. The comic series is known as Cyanide & Happiness.
 - This one is another comic series. This series is called Ctrl+Alt+Del. - This website has a huge database of guitar tabs. I use it often to learn how to play new songs.
