First is the webcomic "Scandinavia and the World". Each character in this comic represents a different country. God it's just fantastic... sooo... yeah... check it out, you won't regret it! = )

Another that can take days to read all the way through is MS Paint Adventure's "Problem Sleuth" and "Homestuck". These comics are done in the style of text based adventure games. Problem Sleuth gets pretty complicated near the end, but not nearly as much as Homestuck, so I strongly urge you not to skip ahead in the stories and read them both all the way through. (they are not directly connected as of yet, so you can read either one, but choose one and stick with it. X D ) Oh also, Problem Sleuth is finished, but not Homestuck.
Next for people who like watching videos of funny critics (like I do.) there's the Nostalgia Critic. He's damn funny and reviews stuff that would be from most people's childhood. (If they're under 35.) But yeah, give him a try!
And for those of you who love ranting comedians there's iLL WiLL PreSS's "Neurotically Yours" with Foamy the Squirrel, also there's 2 the Ranting Gryphon and his show 2Sense. Honestly anything from Neurotically Yours is amazing so give it a try. 2's show 2Sense is really good, though they don't have some of the older episodes on there, but you can watch a lot of them, also he has some of his rants (videos and audio rants.) on there too. enjoy!

And for those of you who never want to sleep again, there's Stumble Upon. This is like a search engine... only you just tell it your interests, and it will pull up random websites related to that. You can spend HOURS AND HOURS AND HOURS AND HOURS AND HOURS on it. Believe me. But it's great. X D
