Here, almighty science wizard Zorglub's conscripted soldiers salute their leader by pointing to their heads with their index fingers to cynically underline how much of a genius they consider him to be. In the Marvel Comics universe members of the organisation Hydra salute in a similar way to a fascist salute but instead raise both hands with fists clenched. This is also accompanied by chanting "Hail Hydra". In the 1987 parodic science fiction film "Spaceballs", directed by Mel Brooks, all subordinates of Supreme leader President Skroob salute him by first bending their forearms over their opposed hands as though they are about to give him the arm of honor salute, but at the last moment, use their raised hands to wave him good bye, rather than showing him the middle finger. In the manga "Attack on Titan" the members of the armed forces (and sometimes civilians in a show of respect towards military) salute by bending their arms and placing their clenched fist over their hearts. The gesture, known as "offering hearts" is meant to demonstrate that the soldiers are willing to give their bodies and lives to protect humanity and to ensure its survival. In the BBC TV science fiction comedy "Red Dwarf", Arnold J. Rimmer continually performs an elaborate special salute that he has invented for the Space Corps, in spite of the fact that he is not a member of the Corps. It consists of extending the hand out in front of the body, palm down and rotating it about the wrist five times (to represent the five rings of the Space Corps) followed by bringing the hand close to the head with the palm facing out.
