I think truly the best asexual rep out there is Perry the Platypus and that is because nothing about his character and none of his storylines have anything to do with the fact that he's asexual, he's just a secret agent who beats up an evil scientist on a daily basis and loves his family more than anything else and that's always treated as a totally normal and completely fulfilling life for him
I always think about how quickly Dan and Swampy said "NO" when asked if Perry would ever have a girlfriend in AYA, and how immediately Dan said, "Does asexual count?" when asked if Perry is queer, I think it's something they always knew about him (even if they didn't think of it as him being "asexual" before that word was more widely known) and I love that they never made a big deal out of it, he just exists as an asexual guy (well, platypus) and I love that so much
I love it whenever creators of animated shows are given the opportunity to voice act in their own show, and end up playing the silliest little creechur imaginable.
Thinking about when Dan Povenmire confirmed that many of the jokes in the shows were just things that they thought were funny at the time and how the writers there clearly have such a passion for their craft that they reuse the same jokes over and over again. Like it's genuinely so sweet. Shout out to the unicycle joke and "secretly I'm very lonely".
