罷工

罢 = 去 + 罒 : Beelzebub (b) is on a strike (罢) in the ashram's bathroom (a4). He is not a Sissy though, so he locked his arms in a concrete barrel (去) hanging right under the floor in a net (罒) so he is hard to get at. He will shout at anyone who wants to use the toilet until his demands are fulfilled.

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.
