認人兒

认 = 人 + 讠 : Robinson Crusoe is lost in the encampment's bathroom. He doesn't know anyone, and he doesn't recognize the environment! At first, he turns to an advertising column, but it doesn't tell him anything useful. But fortunately, Neanderthal Man comes in, instantly recognizes Robinson Crusoe, and tells him where he is.

人 = 丿 + ㇏ : Mnemonic symbol: Neanderthal Man (人). Robinson Crusoe (r-) is looking for snacks in the encampment's kitchen (-en2) when he suddenly spots Neanderthal Man (人). Neanderthal Man offers him a banana (丿), but Robinson Crusoe doesn't trust the present and pokes it with a finger (㇏).

儿 = 丿 + 乚 : Mnemonic symbol: "son" (儿) sounds similar to "Sun" like in "Sun Wu Kong", so it's gonna be represented by the monkey king. Albert Einstein (Ø-) and Sun Wu Kong (儿) are fighting in the space station's kitchen (-Ø2). Their weapons: Albert Einstein has a shovel (乚), and Sun Wu Kong has a banana (丿).
