"Hey, uh, Joe? What's this symbol mean?"
"The big yellow triangle here, with the three black pie slices around the little black circle."
"Oh that. That's just government stuff. Whenever you see one'a these trucks with these diamond shapes and this little feller' or his pals in it, that's the government ID system and whatnot."
"But what's --- 'Radioactive' --- mean?"
"Well dang, ain't it obvious? Means there's a radio running inside, that is to say, a radio is active."
"Shoot! Then we should open this up and turn that radio off, oughtn't we?"
"I dare say you've got the right of it: which if we don't, the government will know where we took the truck!"
"Could you imagine? How stupid would we look then!"
