What was the anime that got you into ANIME?

I only got really sucked into ANIME because of Steins;Gate. This isn't the first time I watched anime, but it was the first time anything really kept me at the edge of seat. Hell, I binged watched the whole thing in about two days. Laughed my butt off and cried my eyes out several times. Oh, how I do love ANIME! I'm sure all of you had good memories from watching ANIME.

So what's your ANIME?!

EDIT: and tell me WHY?!
