竖笛

竖 = 収 + 立 : In the space station's bathroom (Ø4) Sheldon Shrimp (shu) is experimenting with different ways of putting a radio (収) on top of a vase (立) in order to use the vase as resonating body to improve the sound quality. In the end he decides that the best way to put the radio is to set it up vertically (竖).

笛 = ⺮ + 由 : Dorothy Gale (di) had too many cuba libres (由) in the space station's kitchen (Ø2). She mistakes a bamboo stick (⺮) for a flute (笛) and tries to play a melody on it, even though she doesn't know how to play the flute (笛) at all. She must be really drunk!
