焊工

焊 = 火 + 旱 : The marmot (旱) is considering to move in with Hamlet (h) and visits him in the anthill's bathroom (an4). To welcome the marmot, Hamlet is welding (焊) a steel sculpture displaying the words "to pee or not to pee!". The sparks caused by the welding set the whole anthill on fire (火) though and so the marmot runs back to its burrow.

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.
