Background
Sigmund "Siggy" Freud is a psychologist in Vienna, Austria.
During the events of Bill & Ted's Excellent Adventure (1989) played by Rod Loomis
Bill S. Preston, Ted "Theodore" Logan and the others arrive in Vienna, Austria in 1901 and kidnap Freud, followed by Kassel, Germany in 1810, where they kidnap Beethoven during one of his performances. They travel to Orleans, France in 1429 and take Joan of Arc with them and then go to Outer Mongolia in 1209 where they entice Genghis Khan to join them with a Twinkie. They then travel to Washington, D.C. in 1863 where they kidnap Abraham Lincoln. While they are traveling, they notice the antenna is broken. In San Dimas in 1,000,000 B.C., Bill and Ted manage to fix the antenna with chewing gum and pudding cans and take off in front of Neanderthal 1 and Neanderthal 2.
They land back at the Circle K where they first met Rufus and gave advice to their now past selves and then travel to San Dimas in the future for their exam. Missy/Mom makes Bill do his chores and he with the help of Ted and the historical figures finish them all. Afterwards they go to the San Dimas Mall. Bill and Ted leave the historical figures at the food court while they look for Napoleon.
Billy the Kid and Socrates see two women eating at the food court and try and flirt with them. Freud walks over and also tries to flirt and Girl at Mall calls him a geek and she and her friend get up and leave. Eventually all the historical figures are arrested and brought to the Los Angeles County Sheriff, San Dimas Station. Police Psychiatrist starts questioning Freud and Freud in turn, asks him about his mother. Bill and Ted manage to rescue the historical figures and drive back to their school. Bill and Ted give their report where each historical figure gives a speech culminating in Lincoln's speech to be excellent to each other and party on dude. Bill and Ted then leave in the telephone booth to return the historical figures.
