If you were going to make a joke about the Greek gods' choices in sexual partners, you could do a lot better than a homosexuality joke. For instance, you could talk about Zeus's penchant for fucking anything with four legs, or his penchant for fucking his relatives.
Hey, I love Fantasia 2000. Rhapsody in Blue and Carnival of the Animals were great.
My favourite part of Superman/Batman was Superman's unexpected snark streak. He's kind of like Betty White on Golden Girls: you think he's so sweet and innocent and then BAM snark attack! It works especially well since Batman (when not written by Joe Kelly at least) is so humourless.
