They say it's the sincerest form of flattery for a reason. It actually is pretty funny. My favorite is the ad at the top of the fake one. "Your mom is looking for a good developer." LOL
SvN: Sketching with a Sharpie
Ballpoints and fine tips just don’t fill the page like a Sharpie does. Fine tips invite you to draw while Sharpies invite you to just to get your concepts out into big bold shapes and lines. When you sketch with a thin tip you tend to draw at a higher resolution and worry a bit too much about making things look good. Sharpies encourage you to ignore details early on.
The 38th Signal
Wireframing with the blood of your enemies
Ballpoints and fine tips just don’t convey the same sense of malice and dominance as blood. Fine tips invite you to draw while blood invites you to visualize your concept obliterating the competition. When you sketch with a thin tip you tend to spend too much time worrying about making it look good. Using blood encourages you to ignore extraneous details and focus on what matters: the annihilation of your rivals and the subjugation of their people. You can almost hear the women weeping.
UPDATE: Fixed the 38th link above to be a permalink to the referenced article, now that they've started adding parody posts to match some other SvN content. Full site here.
