Mnemonic symbol: ten feet are about 3 meters, so let's say Bigfoot. Nice side effect: that way it's easier to remember 丈夫 = husband (if your husband looks like Bigfoot). The ten feet tall Bigfoot (丈) just left the anglepod's bathroom (ang4), and he left something that looks like a big flute (一). James II of England (zh) needs to move it out of the way, but he'll touch it only with pliers (丈).

㇏

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 (㇏).
