Otto Sylvester Mann (born January 18) is a former school underachiever who now drives the school bus for Springfield Elementary. Otto was initially conceived by Shearer himself as a caricature of heavy metal music aficionados who mostly play guitar and use drugs while occupying a low-level labor job. He then became a character well known for his party tendencies and calling others slang such as 'dude', 'lady', or 'pops'. He is friends with Bart on some occasions, despite their age difference, and dreams of starting his own rock band to become a celebrity, all while getting the school bus into trouble one time after another. Otto is notable for being the cool, pot-smoking bus driver, maniacal driving, love of heavy metal music, and propensity for the 1980's junkie lifestyle. According to his driver's license he was 29, as of 'The Otto Show.' He is also confirmed to be 5 ft 10 inch (5'10), on the back flap of the Season 15 box set, showing said license to hold the guide. Otto has apparently graduated from Brown University, as shown in 'Lisa Gets an 'A''. However, due to this information being revealed in a dream, it might be non-canon. He was placed under suspension at least twice: Once after he not only crashed a school bus full of kids for the fifteenth time but was also revealed not to possess a driver's license and another time when he spanked Bart out of fury after Bart stole the bus (and thus cost him his one and only chance of proving himself to Metallica by giving them a ride).
