罷課

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.

课 = 果 + 讠 : Karl Marx (k) notices an advertising column (讠) in the elevator's bathroom (e4). He decides to teach these capitalists a lesson (课) and throws grapes (果) at the ads, messing them all up. That'll teach them!
