'I, the undersigned, Valentine Michael Smith, sometimes known as the Man from Mars, do grant and assign to Peerless Features, Limited, all and exclusive rights in my true-fact story to be titled I was a Prisoner on Mars in exchange for—" (3.102)

But he was happy that the flavor had been suitable for communication between water brothers—although touched with something disturbing and terrifyingly pleasant. (4.51)
Language gets stickier for Mike and his understanding of Earth. Unlike the quote above, Mike doesn't understand the definition of the words—what we word geeks call denotation—but he does get meaning from them all the same.
