Best One:
http://smashboards.com/threads/project-m-demo-3-sneak-peek.335378/For those who don't know, Project M is a modification of Super Smash Brothers Brawl, to make it more like it's predecessor Melee. In other words, faster pace and much more "combo" oriented.
However, this video (a preview of the next version) is just INSANE. It's like turning the Super Smash Brothers franchise into Marvel vs. Capcom 3. I died laughing.
Worst One:
(A woman I know on Facebook)'s husband decided to pull a nasty April Fool's Day prank on her and turn his FB status to "single". However, considering that their relationship was in a really rocky place, and that she was already considering leaving, she took it as a grave insult, and a form of passive-aggressive behavior, where the "joke" was a form of a plausible deniability for the malicious intent of his actions.
Now she's talking about packing up her things (and her kid) and leaving her, and she's completely serious. Bad move dude.
