“On seeing for the first time a duck land quacking in a pond, Washoe gestured “waterbird,” which is the same phrase used in English and other languages, but which Washoe invented for the occasion. Having never seen a spherical fruit other than an apple, but knowing the signs for the principal colors, Lana, upon spying a technician eating an orange, signed “orange apple.” After tasting a watermelon, Lucy described it as “candy drink” or “drink fruit,” which is essentially the same word form as the English “water melon.” But after she had burned her mouth on her first radish, Lucy forever after described them as “cry hurt food.” A small doll placed unexpectedly in Washoe’s cup elicited the response “Baby in my drink.” When Washoe soiled, particularly clothing or furniture, she was taught the sign “dirty,” which she then extrapolated as a general term of abuse. A rhesus monkey that evoked her displeasure was repeatedly signed at: “Dirty monkey, dirty monkey, dirty monkey.” Occasionally Washoe would say things like “Dirty Jack, gimme drink.” Lana, in a moment of creative annoyance, called her trainer “You green shit.” Chimpanzees have invented swear words. Washoe also seems to have a sort of sense of humor; once, when riding on her trainer’s shoulders and, perhaps inadvertently, wetting him, she signed: “Funny, funny.”
