Possums??

What are possums about? Were they really on Noah's Ark? If so, why? What value do possums provide to the ecosystem...they eat trash or something? Can't raccoons eat all of our trash instead, I mean at least they aren't so ugly. They might be evil little buggers, but at least they can rep solid brands like La-Z-Boy in TV ads. When have you ever seen a possum in a TV spot? Maybe if someone starts offering cruises on the River Styx in hell they'll decide to put some possums in their campaign, but even then, I don't know. I kind of feel like we should set all possums on fire...
