It's Wednesday, so you're probably mad about something -- most likely the fact that it's Wednesday. Well, get out your aggression at the Cheezburger Network via its new site, Rage Comics.
Rage Comics is a new addition to the Cheezburger Network's Memebase and plays off of the popular FFFFffffuuuuu Rage Guy meme (with varying degrees in "f" and "u" duration), a series of comics that took off through 4chan’s /b/ board in late 2008. Basically, the comics are created to express rage. Go figure.
Rage Comics contains FFFfffuuuu comics galore, and it also features a "Rage Builder," making it easy for you to create your own.
