So when I realized that tomorrow's imminent arrival of Stupid Internet Joke Day (was: April Fool's Day) would require the avoidance of all unnecessary internet contact, it also occurred to me that I may as well point out some common Funny Anti-Patterns. But that's been done to death - thank you, internet hipsters.
I merely wish to remind you all that elaborate hoaxes (press releases involving small company acquiring a large one, switching stylesheets with someone, etc) are immediately and transparently stupid. Instead, try to actually do something surprising. The ha you save might just be your own.
