二話不說

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).

话 = 舌 + 讠 : Helga Horse can't talk at all right now, because her tongue is stuck on an advertisement column in the ashram's bathroom. In an ad on the advertising column, two people were discussing a depicted beautiful carrot; Helga thought it looked so tasty she had to lick it, and now her tongue is stuck.

不 = 丆 + 卜 : Bruno Bear (bu) is setting up a wind wheel (丆) with a voodoo staff (卜) in the space station's bathroom (Ø4). He also puts a "forbidden" sign (mnemonic symbol for 不) on it, to make clear that it may not (不) be stopped.

说 = 兑 + 讠 : In front of the observatory is a big advertising column. On it is a picture of Sheldon Shrimp, who is depicted to be talking about his new cash exchange booth.
