第二职业

第 = ⺮ + 弓 + 丨 + 丿 : Dorothy Gale (di) accomplished an awesome result with her composite bow (弓) in the space station's bathroom (Ø4): She shot a banana (丿) onto a dinosaur bone (丨) so the banana was split in half, and then fired a bamboo stick (⺮) into the banana (丿) so the banana was split in half as well. Dorothy is number one (第) with the bow!

二 = 一 : Mnemonic symbol: a capacitor, because the two strokes remind me of the symbol in electrical drawings. Albert Einstein (Ø) is experimenting with a capacitor (二) in the space station's bathroom (Ø4). He finds that it's uncomfortable to discharge a capacitor using two flutes (一).

职 = 只 + 耳 : James II of England (zh) has to visit the governmental office (职) in the space station's kitchen (Ø2) to ask about his taxes. There's a cuttlefish (只) on duty, and James literally has the cuttlefish's ear (耳).

I can't help but see a bullfrog in 业. Maud Younger finds that the climate in the elevator's bathroom are perfect for her new business: growing bullfrogs.
