各取所需

各 = 口 + 夂 : Mnemonic symbol: each and every (各) one of us is made of atoms, of which most were created in a star (from lighter atoms). That's why I choose to represent this character by a star. Guy Fawkes (g) is stepping on a mandarin (口) with high heels (夂) in the bathroom of the elevator (e4). As he squeezes, the mandarin suddenly explodes in a rain of stars (各). Each and every (各) one of them is shining brighter than the others.

取 = 又 + 耳 : Mnemonic symbol when used as component in other characters: a bloody ear.

When Mike Tyson was fighting against Evander Holyfield, he did not only beat Evander's ear (耳) with his boxing glove (又). Imagine this fight in the space station (Ø3) with cupid (qu) as referee fetching (取) a bloody ear flying through the space station.

所 = 戶 + 斤 : Susan Saint Bernard and her whole family are weight lifting in the place of the observatory. They are all together lifting one barbell.

需 = 而 + 雨 : Mnemonic symbol: When it rains and you do not want to comb your hair again, you need a rain cape.

需 = 而 + 雨 : It is raining in front of the rain station. Because Xu Xian doesn't want to comb his hair again, he uses a rain cape to stay dry.
