Today featured some really fun suggestions things, and I'm happy to have played the part in them that I did:
Commemorative Big Red Button vgift or Real Big Red Button (some people would buy these for real)
Sponsored Userpics (this is a JOKE, o mighty marketing department)
I usually find something to pull on my best friend. Not this year, though. I did e-mail him.
Not April Fool's related, but pretty awesome: brooklynmili is presenting two papers, including an X-Files paper(!!): http://brooklynmili.livejournal.com/34759.html
