Oh huh, one of the weird caveman dioramas. Is “Rad-los” his name? I guess it must be, but that strikes me an an uncommonly strange name for a caveman. Even a caveman farmer. Even a caveman farmer who is kind of retarded and has decided that strapping his cart to a turtle will get him there faster than just carrying the hay himself. Which I guess is the intended joke. What’s way funnier, though, it the look of paranoid terror on Rad-los’s face. He thinks that tree is going to assassinate him.
"Rad-los" means "wheel-less," though it sort of seems to me that there shouldn’t be a hyphen.
