I need some more anime from the "random insanity" genera. Anyone care to offer suggestions?
Seen: Excel Saga, Puni Puni Poemy, Nurse Witch Komugi, Beat to Death Angel Dokuro-Chan, & 2x2 Shinobuden
Melancholy of Haruhi Suzumiya wasn't on your list? I'm surprised.
EDIT: it's so random that even the episodes didn't broadcast in order. Okay, so Haruhi isn't as crazy as Dokuro or Excel Saga, but I still think it falls under the same category of "random insanity".
Sexy Commando Masaru is pretty crazy. You should try watching it.
My suggestions:
Dragon Half
Ping Pong Club
Photon
FLCL
Ursuei Yatsura
Although not as crazy or insane like Excel Saga, these are fun to watch too.
I thought there was plenty of random insanity in Azumanga Daioh. Great humor paired with interesting characters.
Other suggestions not mentioned before:
Magical Shopping Arcade Abenobashi (persiflage galore)
Cromartie High School (crazy stereotypes in an undisclosed plot)
Hare + Guu (rumble in the jungle)
Kekko Kamen (hilarious classic)
Child's Toy/ Kodomo no Omocha (random fun with Sana-chan)
Cat Soup (not hilarious but definately insane)
Dead Leaves (total mayhem)
DiGi Charat (the original 16 ep series, not the other ones)
Animation Runner Kuromi 1+2 (not that random but still funny as hell)
... and maybe some episodes of His and Her Circumstances/ Kare Kano.
How about Digasea or Ebachu-the House Cleaning Hamster-this has got to be just about the craziest series I've ever watched.
