虛實

虚 = 业 + 虍 : Xu Xian (xu) and the bullfrog (业) were preparing for a football game in front of the space station (Ø1) and had already painted eye black stripes (虍) onto each other when suddenly a black hole (虚) appeared and sucked their eye black off again before collapsing.

实 = 头 + 宀 : Sherlock Holmes welcomes professor Skull just inside the entrance of the space station. Professor Skull has not a complete head but only a skull, and a solid understanding of solid state physics. She really is an honest person and still wears her graduation cap.
