胸廓

胸 = 匈 + 月 : Xu Xian (xu) noticed Bela Lugosi (匈) is just going out when the full moon (月) is shining at the night sky and suspects that he is a vampire. Therefore, he plots against Bela and one month later, he rams a stake into Bela's chest (胸) in front of the engine ((e)ng1). Bela just feels a little chest (胸) pain but nothing more, since Xu Xian missed his heart.

廓 = 广 + 郭 : Karl Koala (ku) is practicing his skydiving skills in the observatory's bathroom (o4). He set up a big (廓), open (廓) ring of outer city walls (郭) which he tries to land in when he jumps from the ceiling with his parachute (广) on.
