I didn't have a problem with the phrase "ton of paper". I just picked that example because I thought the two clauses of the sentence didn't fit together well and the double use of the word "paper" was jarring. Maybe, "Gregory's cluttered bedroom contains at least a ton of paper." Or, "Gregory’s bedroom is filled with paper; it contains a literal ton of printouts, articles, and magazine clippings." IANAW though. And I don't know what a literal ton is.
