>Name any anime
>They'll probably watch it
BOKU NO- *shot*
I dunno what else to choose. If I had to choose, it'd be mainstream stuff like Haruhi, Evangelion, Code Geass, Fullmetal Alchemist, and Lucky Star, I guess.
wow, I wasn't expecting that to come out here XD
It really depends on the genre you're into. Evangelion and Akira are generally considered a staples for old-school fans. Same goes for a lot of the Miyazaki ones. Dragonball for the 90s generation, TTGL for the newer generation since there's a nice chunk of memes spliced from that.
Oh, though I would say Princess Tutu is a series everyone needs to watch at some point.
Wow, thats one anime series I'm not going to watch :/
heh, I need to go watch it at some point being a mecha fan and all. The main thing about gundam is that there's different timelines, so series like 00 is standalone, same for the SEED series, Wing, and G Gundam
EDIT: Here's probably my general list of things you should watch. They're a bit skewed due to recency, how often they're mentioned around me, memory problems, and more, but for each one, this is generally a list I'd recommend off the bat. [Shounen's a bit weird to choose due to the determination of Shounen, but nyeh]
