Ernest Keigel is the fictional and stereotypically snarky and fast-talking Time Ranger, whose penis is a time machine. When he masturbates, he travels through time, ending up in a time and location where he is needed most. He cannot normally be seen and it is joked that he is a eunuch because of his "time machine's" minuscule composure. He's also a polygamist.
- The movie The Shoulder of Orion II, also used the idea of using masturbation to time travel.
