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 : When Mike Tyson was fighting against Evander Holyfield, he did not only beat Evander's ear with his boxing glove. Imagine this fight in the space station with cupid as referee.

取 = 又 + 耳 : In other characters: A bloody ear.

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.
