山地车

山 = 丨 + 凵 : Mnemonic symbol: 山 looks like the tip of a fork. Sherlock Holmes (sh) is climbing a mountain (山) in front of the anthill (an1). He uses a dinosaur bone (〡) as walking stick, and to have better grip he attached a fork (山) to its tip. Unfortunately he accidentally sticks the fork into a receptacle (凵) on the ground of the mountain and gets shocked.

地 = 也 + 土 : Dorothy Gale (di) hates the cleanliness of the space station, so she used an excavator (也) in the space station's bathroom (Ø4) to dig a pile of dirt (土) out of the ground (地) for a mud bath.

车 = 七 + 十 : Charlie Chaplin (ch) is parading in a cabriolet (mnemonic symbol for 车) in front of the elevator (e1), because he wants to establish his new cult. Like all successful leaders, he takes the carrot-and-stick approach: In one hand he's waving with a seven-branched laser sword (七), in the other one he's waving with a cross (十).
