> the 900 pound, white elephant in the room Interesting phrase, a mixture of at least three phrases: - "800-pound gorilla" (https://en.wikipedia.org/wiki/800-pound_gorilla https://en.wikipedia.org/wiki/800-pound_gorilla) -- something big that can do whatever it wants - "white elephant" (https://en.wikipedia.org/wiki/White_elephant https://en.wikipedia.org/wiki/White_elephant) -- an expensive but useless gift or thing - "elephant in the room" (https://en.wikipedia.org/wiki/Elephant_in_the_room https://en.wikipedia.org/wiki/Elephant_in_the_room) -- something obvious that no one wants to discuss. It's not clear which meaning you're trying to convey. C is definitely not useless, so I imagine that the "white elephant" part at least is not intended. Note that an adult elephant weighs several thousand pounds, so a 900-pound elephant is probably a baby elephant.
