Otto Mann is a fictional character on the American animated TV series The Simpsons, voiced by Harry Shearer. He is the school bus driver for Springfield Elementary School, and is known or implied to be a user of several drugs.
Otto, who is of German descent, is notable for his maniacal driving style (which, along with never getting a driver's license, cost him his job on the season three episode "The Otto Show"), his love of heavy metal music, and his propensity for sounding and acting like a perpetual 1980s teenager. At the end of this episode, according to his driver license, Otto is 5'10", weighs 150 pounds and was born on the 18th of January, 1963.
In season eleven's It's A Mad, Mad, Mad, Mad Marge, he is shown to be a big fan of glam metal group Poison. According to A Complete Guide To Our Favorite Family, his favorite songs are "Free Bird" by Lynyrd Skynyrd, "Purple Haze" by The Jimi Hendrix Experience, "Frankenstein" by the Edgar Winter Group, and "Iron Man" by Black Sabbath. He also showed he is a fan of Metallica, when he allowed the school bus to be hijacked by Bart Simpson, while unsuccessfully trying to offer them a ride. He also is very proficient at playing the electric guitar as he played a lot in high school, but his father's disapproval meant he never became a guitarist of a rock or metal band, when he proved to Bart that his was not broken (season 3 episode 22: The Otto Show). That was more noteworthy because Bart's guitar is left handed, and Otto played it right handed by just turning the guitar upside down. Despite it all, he hates standing and jumping in mosh pits, as proven when U2 played Pride (In the Name of Love).
In the episode "Bart's Inner Child", Otto jumps on a trampoline designed for kids, demonstrating his immaturity. He also has a habit of describing things as "gnarly". In early seasons he is often used as a friend and confidant to Bart, despite their age difference. Later seasons however usually only depict him as a passerby citizen of Springfield.
He has been seen at Alcoholics Anonymous meetings: "My name is Otto, and I love to get blotto!" He is a stoner as well (he smokes with Homer in "Weekend at Burnsie's", had a joint with him on "Strong Arms of the Ma", and smoked a bong in The Simpsons Movie). It has also been implied that Otto used other drugs like LSD (in "Homerpalooza", during Peter Frampton's show, he sees his shoes talking to him; in "The Seven-Beer Snitch", Otto's urine sample was so loaded with illegal substances that the inside of it looked like a scene from the cartoon Yellow Submarine; and in a promotion for season 30 he described the afterlife as “mushrooms, mushrooms everywhere”). His openness towards substances is also demonstrated in the new HD intro, in which Otto ingests the plutonium rod that Homer tosses out from the Springfield Nuclear Power Plant.
