罂

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.

贝 = ⺆ + 人 : Mnemonic symbol: a crab. In the Eiffel Tower's bathroom (ei4), the Neanderthal man (人) and Beelzebub (b) are fighting a crab with staplers (⺆), but because the Neanderthal man (人) can't handle the stapler he accidentally staples himself in the forehead.
