A cunning plan

Who: Cerebrum, Trisees, Keto, Jay, everybody else on the planet
Where: Guess
> Jay shook his head, and pointed. Keto and Trisees turned to see
> what had got him so anxious.
> "Ah..." said Keto.."Dinosaur..."
Cerebrum turned around and looked at the dinosaur, still holding his
notebook and wishing like hell that it was a machine gun. "From what
I can tell," Cerebrum said, "we have several choices at this
juncture. We can stand here and get eaten by this dinosaur. Or we can
run away from it and let it chase us, and then it would catch us and
we'd get eaten. Or we could climb a tree, in which case we'd get a
nice view of the jungle until the dinosaur knocked down the tree and
ate us."
Cerebrum slowly backed away from the dinosaur. They didn't tell you
about things like this in psychiatric school. They told you how to
treat maniac depression, not once did they mention how to escape a
dinosaur when it was going to eat you. He didn't even know what kind
of dinosaur it was, since knowledge of extinct species wasn't a
requirement to become a psychiatrist. However, with his knowledge of
insticts and behaviors of creatures, he had managed to formulate a
working plan.
"Though I think I've figured out option four. We all run away, but
run faster than Dr Keto. As the dinosaur eats him, it'll give the
rest of us time to get away. Anybody got any problems with this plan?
Besides Dr Keto. Don't worry, Keto, I'll make sure they give you a
post-humous medal of honor after we contact the Blue Dwarf."
