Spotted two so far:
Locus Online with the usual run of gags (a little disappointing this year, for me anyway)
Kingdom of Loathing (just go there — read through the titles)
Updated: Teresa Nielsen Hayden at Making Light points out several more
AND: Ed Champion is cracking me up.
Did you see Google Romance?
kingdom of loathing has been overloaded all weekend, so i couldn’t see it. boo.
