宋四家

宋 = 宀 + 木 : Susan Saint Bernard and Mr. Song are celebrating Christmas in the engine's bathroom. They're presenting their big hats and their even bigger butts.

四 = 儿 + 囗 : Mnemonic symbol: a four-leaved clover. Socrates (s) is working out in the bathroom of the space station (Ø4). He's lifting four (四) wooden boxes (囗), and wonders why they are so heavy. He doesn't know that inside one of the four boxes, the monkey king (儿) is hiding and secretly laughing at him - until the monkey king comes out and surprises Socrates with a four-leaved clover (四).

家 = 宀 + 豕 : Mnemonic symbol: a framed "home sweet home" picture.

The swine (豕) graduated and wearing a graduation cap (宀), it came home to the ashram. In front of it (a1), Joan of Arc (ji) welcomes the swine and hugs it. To welcome her dear swine, she put a gigantic home sweet home (家) picture in front of the ashram.
