Here are some concepts for the possum that may lead you into a routine:
Former cocaine addict. The white line seems to hypnotize him. That's why you see so many possums on the highway.
He became a truck driver to overcome his fear of the highway. Use 10-4 good buddy, what's your 10-20, etc. Now he has to learn how to use text messaging.
Animal facts bit:
V: This is Awesome Possum. He is a unique animal. He is a marsupial. Tell them what that means.
F: It means that I'm from Mars. I look like Stitch.
V: You have a pocket.
F: I don't have a pocket.
V: Yes, you do.
F: I don't even have pants!
V: A marsupial has a pouch. It is made from extra skin on their belly.
F: I see you're working on a pouch too!
V: The possum keeps something very special in their pouch.
F: Yes. My pocket nintendo.
V: (ignore him)
F: A pocket book.
F: My library card.
V: You keep your babies in the pouch!
F: OH! Now I understand! No, you're thinking of the female possum! I'm the male!
V: Thank you for correcting me. When a baby possum is first born you could fit several in a teaspoon.
V: They crawl into the pouch where they find nourishment from the mother.
F: What is that?
V: Something to eat!
F: Chinese take-out.
V: The mother gives them milk.
F: They like chocolate.
V: That means the possum is also a mammal. Another unique thing about the possum is its tail.
F: Really? It looks a lot like my nose. Sometimes I can't tell if I'm coming or going.
V: It has a prehensile tail.
F: You don't have to make fun of me!
V: That means that you can hold on to things with your tail.
F: I like to hang upside down in trees. It gets the kinks out of my back.
V: Possums like to come out at night.
F: We are PARTY ANIMALS! Whoo-hoo!
V: They are often found trying to cross the road.
F: To get to the other side. (or some joke here)
V: But the lights from the cars hypnotize them.
F: What? That's the most ridiculous thing I've ever...
(facing a spotlight or the lightbulb)
V: Awesome? Awesome? Oh, no! I think he's mesmerized by the light! He's going to be out for awhile. (Hold him upside down.) Sometimes he will act like he's dead in order to avoid danger. (slip him back on somehow)
F: Where am I?
V: I was beginning to wonder about you.
F: I must have blacked out. All I remember was seeing a bright light at the end of the tunnel. But I'm okay now!!!
