句式

句 = 勹 + 口 : Mnemonic symbol: a grammar nazi.

Zeus (ju), the elephant (勹) and the grammar nazi (句) are playing monkey in the bathroom's space station (Ø4). The elephant uses its long trunk to hold a mandarin (口) just above the grammar nazis head where he can't reach it, while Zeus laughs out loud.

式 = 工 + 弋 : I'll use a specific style as mnemonic symbol: 哥特式, gothic.

Sherlock Holmes and the goth are celebrating a Viking festival in the space station's bathroom. They don't have trunks to throw around, so they use a steel beam. They also celebrate by practising archery. In zero gravity it is easy for them to set one world record after the next.
