Me and my friend Andy, when i first found out about DBZ..we stayed up for about 3 days straight watchging it at his place, I got pretty damn tired once we watched all of it that he had xD

I watched the whole series of Fruits Basket in one night, with maybe an occasional bathroom break. About 9 hours +_+

I don't know how long it was, but I watched all three seasons of Aria at one time.
:rheart::rheart::rheart:
and yes, I cried at the end...I always do with Aria...:rheart:

Once, my sister and I watched a dozen episodes of InuYasha in one sitting. We had rented three volumes without knowing that there were four episodes on each one. (For the season before that, there had only been three to a disc.)

Not much, I guess, but it's the longest marathon I've had to-date.

2 day marathon of bleach...since i really neede to catch up..and watched the filler episodes too
-.-

I think it was about six hours. I was trying to finish up the rest of Full Moon so I could go on to another anime. I didn't know if I was crying because of how sad it was or if it was because I was so tired because I had stayed up so late. XD
~C ya
:D

All of Gundam Wing in one sitting X___X;

Several hours, I can't even remember how many! I remember...I finished Ghost Hunt and Sukisho in one sitting...which was...35 or 36 episodes...
I saw episodes 7 to 15 of Death Note one day...then the next day (or the same day/night...I don't remember)...15 to 22...and then 22 to 32...
I watched up to episode 18 in Lucky Star one day, then finished it one night.
I spent a whole day watching Clannad, but I only got to 13...I was watching Genshiken before that. And this is all if no one (someone can, its not like I'll listen :rolleyes:) bothers me.

I have a challenge for myself...for six different anime...

Katekyo Hitman Reborn
D. Grayman
Eyeshield 21
Prince of Tennis
Fullmetal Panic
Case Closed (Detevtive Conan)

And that challenge is to see how far I can get in each one for one day. Yep. No bathroom breaks, no eating breaks. Just me, my computer, and I...what a stupid idea...
