I reckon I have... well, not weird, but "unique" tastes. Personality triumphs over looks for me, so with that in mind, Muffy the Uchi Sheep is who my avatar would date. I can't date her in real life, I have a wife! (Hey, that rhymed! )
Dotty because she's super-cute and adorable and looks just like one of my RL bunnies did. Though Diana is really pretty, too, and I like snooty villagers.
As for the males, I think I like Kabuki the most. We're super-close friends and he has become really sweet. He now dubbed me "missy", though. Not my best nickname, but I take it as friendly teasing. XD
