衰弱

衰 = 丑 + 衣 : Sheldon Shrimp (shu) is feeling very awkward in front of the airplane (ai1). He is on a date with an ox (丑), but the oxen's kilt (衣) is so old and feeble (衰) that it is falling apart.

弱 = 冫 + 弓 : Rachel Rhinoceros (ru) created a piece of art in the observatory's bathroom (o4). She joined many composite bows (弓) by sticking their ends into popsicles (冫) which weren frozen again afterwards. Her whole construction is a huge armchair, but it is very fragile and weak (弱), so Rachel puts on it many of these "handle with care" stickers.
