以免

㠯 = 尸 + 口 : Mnemonic symbol: 㠯 looks like a cool pair of safety goggles.

A ghost (尸) has been hiding from Maud Younger (Ø3) in a mandarin (口). Maud finds the mandarin in the space station's living room (Ø3) and squeezes the ghost out, and in order to (㠯) be protected from the mandarin juice flying all around in zero gravity she is wearing safety goggles (㠯).

以 = 人 + 厶 : So this is Neanderthal Man with a fake nose. He has bushy eyebrows, so my symbol for 以 is going to be one of these fake noses that come with additional glasses, eyebrows, and a moustache: Groucho glasses.

以 = 人 + 厶 : Maud Younger and Neanderthal Man prepared some costumes for Halloween in the space station. Neanderthal Man created a big fake nose, while Maud Younger made a pair of Groucho glasses.

免 = ⺈ + 口 + 儿 : Mnemonic symbol: 免责说明, a disclaimer.

Marilyn Monroe and the crane are on a date in the anthill. Sun Wukong served them cocktails in two mandarins, but the cocktails are so terrible that Marilyn and the crane had to puke all over the place which ruined their date. They want to sue sun Wukong, but he just shows them the place's disclaimer telling them that he is exempted from any responsibility.
