I loved the original Power Rangers theme so cheesy but awesome. I found the show itself generally pretty meh when I was a kid, each series also got progressively worse. Monster designs were pretty funny.
One dorky program I like to watch from time to time is Yu-gi-oh, mostly because I find Yami very attractive.
Here's a list of things that I tend to do outside of Zelda:
Competitive Super Smash Bros. (Mainly Melee and Project M)
Competitive Pokemon
Attending conventions and cons
Merchandise of my favorite franchises
Anime and Manga
Comic books
Toy collecting
Pokemon TCG
Magic: The Gathering
Chess
I'm sure I have more things that I like doing whenever I have the time but as of now these are just some of the few things that I do when it comes to doing dorky things outside of the Zelda fandom.
I'm a huge Star Trek and Buffy the Vampire Slayer/Angel fanatic.
There are several other series, including video game series, that I love. But those two I love the most.
