油 = 氵 + 由 : Maud Younger (y) is creating art in the outhouse's kitchen (ou2). She is painting a picture using oil (油) paint and occasionally using water color stored in a water bottle (氵). She is nipping a cuba libre (由) and from time to time even using her drink as color for her picture.

于 = 亅 + 二 : Mnemonic symbol: prepositions (in, at, on, to, ...) are what glue the sentence together. Honey is as sticky as glue, so I'll represent 于 by a honey jar.

Yu the Great (于) was assigned to repair the electronics of the space station's kitchen (Ø2), but instead he was snacking honey from a honey jar (于). Unfortunately his capacitor (二) got stuck in the honey and now he has to use a crowbar (亅) to lever it out.
