I was with my friends one day, and I used to diss on them hardcore for watching DBZ. I thought it was the stupidest thing ever (of course, I had no clue of the overall story, but still). I was like, "they all look the same, some guy has a ****ing tail, and there's a random green dude for no reason." Yep--I was one of THOSE guys.
Then one day my friends, right before an episode of DBZ, explained the whole overall story to me. And I thought it was an awesome story.
They also explained to me why seeing a single episode was confusing and pointless--that they were all like, four minutes in a series of like 20+ years of events. They asked me to watch it for like, three to five days in a row, and they told me I'd be hooked. I asked them to give me some background on the show that was gonna be on that day...and they told me, "well, this dude who's always been jealous of this other dude just got jacked up and they're gonna brawl. If you're gonna watch an episode, this is the one."
I was like, "why?"
And they said, "Cause this is gonna be the best fight in the show."
So my answer is:
Majin Vegeta Vs. Goku.
'nuff said.
