I rather agree with Syd, actually. I guess I don't mind entertaining AFD jokes that people put thought into (Syd's and YouTube's would be an example), but frankly, I just hate being on the internet on April 1st. So much shit, most of it so irritating. (Probably I'm still just scarred from the IGN Zelda movie prank from last year. Sigh.)
For those who want to keep track, by the way, Kotaku has a regularly updated list of all the major pranks on the web:

(Although frankly, I don't know why the "Epic Sesame Street" joke was put under Ugly. I thought it was rather clever, and the character designs were cool.)
EDIT: my favorite AFD joke so far:
