Sign the petition to Save Big O! (that is, if you haven't already) Just need to get as many signatures as possible!!!!
Head over to http://www.savebigo.com to find out more stuff!
Also, am I the only one who just found out about Adult Swim bringing Big O back starting Novemeber 1? It's at 5AM EST, unfortunately... but I'm still going to to my best to watch it! It's in the Adult Swim lineup here.
