常 = 小 + 冖 + 吊 : Charlie Chaplin is fighting his way through anglepod's underbrush with a coat hanger. The anglepod has not been visited in a hundred years, and with his coat hanger, Charlie Chaplin has to cut down a lot of daisies. Finally he found what he was looking for: the centennial light, protected from the daisies and the rain by a cooking top.

年 = 午 + 丨 + 一 : Nefertiti (ni) is having lunch (午) in the anthill's kitchen (an2). Unfortunately they didn't have any cutlery left so she has to use a dinosaur bone (丨) and a flute (一) instead of fork and knife. It will take her a whole year (年) to finish her lunch this way.
