Given the task definition and input, reply with output. Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no". An acceptable answer is consistent with the context in question, detailed, long, and uses general knowledge of English. Answers that are not definite and suggest a variety of options are not acceptable answers.

Question: It is common in American English to refer to a powerful person or organization as an 800 pound gorilla. The expression makes sense -- a gorilla of that size would certainly be intimidating -- but what's so special about the number 800? Searching "n lb gorilla" on Google for various values of n results in many more hits when n = 800 than when n is any other quantity. Also, the Google Ngram Viewer finds notable occurrences of the phrase "800 pound gorilla" in texts starting around the late 1970s; other sized gorillas don't seem to be mentioned at all. The Wikipedia entry for the idiom claims that the phrase is rooted in a riddle ("Where does an 800lb gorilla sleep?"), but that's just passing the buck. A 700lb or 900lb gorilla would be equally entitled to sleep wherever he wants to. Interestingly, the Wikipedia entry for gorilla states that the average male gorilla weighs about 400lb, occasionally reaching 500lb in the wild. Only obese gorillas in captivity have attained weights of 600lb. So the number doesn't even seem to be related to gorilla biology (except that it is safely larger than any known gorilla, save King Kong). Given that it's an arbitrary figure, is there any reason the number 800 would be more popular than any other? More generally, is there any relevant research into why some numbers would be more popular or pleasing than other in contexts like this?
Answer: Quite large gorillas in the wild are at most 550 pounds; so an 800 pound gorilla is one that's oversized, even fat. As Wikipedia states, this phrase first originated with a riddle, "Where does an 800 pound gorilla sleep?" Ans: "Anywhere it wants." Because this is the standard idiom, when people want to speak hyperbolically they will sometimes exaggerate the number to "1,000 pound gorilla", or some other, even larger number. In short: no, the number 800 does not have any special significance, except perhaps with reference to the typical (male) gorilla's average weight (450 pounds).
