或許

或 = 一 + 口 + 戈 : In observatory's bathroom, Osvaldo Farrés plays his famous song "Quizás, Quizás, Quizás" (Perhaps, Perhaps, Perhaps) on a flute. Helga Horse listens and doesn't know whether she should maybe give him her mandarin as reward, or perhaps stab him with a spear.

许 = 午 + 讠 : Xu Xian just loves having lunch in the space station. In fact he loves it so much that he calls mission control to get permission to praise it on an advertising column. After he got the permission, he smears his lunch all over the advertising column.
