Some humor/random feeds

[orchidfire]

abstrusegoose_feed – For the webcomic Abstruse Goose. You'll enjoy this comic if you like xkcd and PHD Comics. I have an entry with my favorites here.
cyanideandhappiness_feed – For the webcomic Cyanide & Happiness.
mydadisafob_feed – For the quotes blog My Dad Is a Fob.
mymomisafob_feed – For the quotes blog My Mom Is a Fob.
pbf_comics_feed – For the webcomic Perry Bible Fellowship—it's rarely updated nowadays, but I still have hope!
thisiswhyyourefat_feed – For the picture blog This Is Why You're Fat.
wtf_nature_feed – For Livejournal's wtf_nature. Updates have slowed down because it seems that moderation has slowed, but it still updates about once a week and provides some of the best "WTF, NATURE!" moments I've had. :P
