What's the strangest anime you have ever seen?

Utsu Musume Sayuri. There's a reason it has a 2.05 on MAL. You can watch it here, it's only like 3 minutes long, but be warned, it is extremely uncomfortable to watch.

Legend of the Overfiend. full stop. do not pass go, do not collect any kind of money whatsoever.

The strangest one I've seen is Excel Saga, because I have standards.

But dont get me wrong, this anime movie isnt bad for being weird.

Evangelion. Either the story was shit or was extrem complex.

There was this one anime where the girl was an alien in disguise at school. And then someone drooled she did or a random boy who ends up being the protagonist and he gets addicted to it?

There was also another one where this guy get special powers from drinking breastmilk (which I've taken to calling it Breaktmilk Power Ranger and forget its name) and hes legit hanging around with like 6 women most times and if a bad guy shows up he just pure gets them to whip out and glug glug hes super power now.

Then theres one with a perverted teenager, and a fairy and flying underwear. And he gets different abilities for the different girls underwear he puts on his head.

Oh and the gambling one thats on netflix right now. The hysterical, horny screaming at gambling and card games makes me do a solid 50/50 on uncomfy and intrigued.

I really want to say Interstella 5555, but I don't think that's the kind of strange you're looking for

FUBAR: Last episode of 90s version of Berserk

Weird: well, there's enough candidates that I feel like you could make an entire sub-genre of anime for "weird"... hmm. what's the japanese word for that again? :-) But the weirdest one that comes to mind right now is Arakawa Under the Bridge. Akira is a good weird one too at least IMO. Somebody else mentioned Excel Saga, yeah that was weird too. I'm sure there is stuff out there that makes those look tame but nothing is popping out in alcohol fueled brain atm

also, what is wrong with me that for some strange reason I don't consider Ishuzoku Reviewers as "weird" enough?

Rapeman

Ever wanted an anime girl to literally turn into a vehicle? well you can with Henkei Shoujo (Transforming Girls) Which are 1 minute shorts of anime girls turning into machines. For the time it takes to watch, its totally worth it.

that i liked? Mawaru Penguindrum

Sorry for bringing this back up, but I have been watching Assassination Classroom on Adult Swim. That show is SO messed up at times.

This scene from episode 4.

Warning- DEFINITELY NOT safe for kids. I'm not sure it's safe for adults either.

one of the strangest animes ive seen. had me hooked and i ended up watching all of it

View attached image.

Monogatari series, probably my all time favorite.
It is pretty tame, except when it isn't.

The obvious example is this NSFW scene from Nisemonogatari.

Not anime, a U.S. animated movie, but, Coonheads is.... ahem... out there.Fritz the Cat is also far out

Aeon Flux,
Dead Leaves.

well idk about strange but i know something BIZZARE

Weirdest for me is probably Neon Genesis Evangelion. Starts off normal enough, but the end is a mindf*ck (especially the alternate ending / movie End of Evangelion). Great show tho.

Tenshi No Tamago.

Bump.

Space Dandy was definitely an out of the ordinary anime.
