工 = 二 + 丨 : Mnemonic symbol: a steel beam, since 工 looks like the cross section of a steel beam.

Gitta Giraffe (gu) is working a shift in front of the engine ((e)ng1). Her job is to melt dinosaur bones (丨) so that they can be disposed off easily. To melt the bones, she is shorting a huge capacitor (二) with a steel beam (工) which consequently heats up to a bright glow. Using the glowing hot steel beam she can melt the dinosaur bone easily.

缶 = 午 + 山 : Frankenstein's Monster (f) is showing off his art skills right in the middle of the outhouse (ou3). He prepared some pottery (缶) to look at, but that's not all: when the bell tolls at noon, he takes a fork (山) and eats his pottery for lunch (午) as the central element of his art performance.
