Oh boy I have so many, but I'll name the ones I recall the most.
1) Discovering Dragon Ball upon finding literally hundreds of un-opened Dragon Ball figures in my cousins house. I always wanted to play with them, but he wouldn't let me open them. He eventually let me watch his Dragon Boxes. Oddly enough I never noticed his DB manga! I suppose I thought they were just books as a kid.
2) Coming home that exact same day to tell my friends in my neighborhood about an awesome show that was on Toonami. (My cousin wouldn't let me borrow his DBoxes so he told me about Toonami)
3) Watching my cousin draw Dragon Ball and Mortal Kombat all the time, I always wondered why he drew everyday. It took me literally until I was probably 16 to put together that he was inspired to be a Manga artist since DB was his life, and it came from a manga.
4) My father buying me GT Transformation and a GBA SP for my Birthday!
5) Playing Budokai 1 and 2 with my friends and cousins 24/7 on PS2.
6) Anxiously awaiting for my mother to return home with Budokai 3 at a night release, and my father letting me stay home from school the next day to play it. (She also got me a 2nd PS2 memory card!)
7) Buying any magazine with Dragon Ball on it from random general stores, like "How to draw Goku!"
8 ) Staying up late with my friends to watch DBZ on Toonami, I recall Pokemon with a different cast airing after. I think it was called Pokemon chronicles.
9) Literally after an episode of DBZ went off, a friend asked why there weren't any "Fighting Cartoons" like DBZ and Naruto came on right after. Thanks to Toonami and DBZ we were introduced to Naruto.
10) Walking through my neighborhood with friends at night, looking up at the moon pretending to turn into a Giant Ape (Oozaru).
11) Sitting on my steps during the summer playing Buu's Fury for GBA SP awaiting my friends to get home from going shopping with their parents.
12) Arguing with my friends that DBZ was still better than Naurto and Avatar.
13) Finding DBZ figures and toys in places they shouldn't have been, like this clothes only thrift-shop my grandma used to go to.
That's not even a crack into my subconscious but I don't want to bore you with my DBZ based childhood!
(DBZ, Yu-Gi-Oh!, Naruto, and Pokemon were probably the anime we all liked the most and it's the only connection I have left now with the friends I grew up with. I think that is why DBZ itself is so precious to me.)
