A Feeble Attempt At Humour

My eldest child is given to setting impossibly convoluted puzzles for me to solve. (We think he may be slightly autistic.) One of his favourites is to give a crossword-style clue for a word, along with the "weight" of the answer. (Each "a" is worth one ounce, "b" two ounces and so on.) This morning over breakfast, he tested me with "The carcass of a dead animal, four pounds and fourteen ounces." I thought for a moment before replying, "'Carrion', my weigh-word son."
