<P> Steve does not share many interests with his sister, Hayley, but has occasionally collaborated with her on schemes, such as when they tried to break up a young couple so Hayley could get the guy and Steve the girl, which ended up backfiring on both of them getting the couple killed . They have also tried to teach both of their parents individual lessons, like when they tried to teach Francine not to be racist, only to learn that she was actually prejudiced against left - handed people, or when they exacted revenge against Stan for turning a homeless shelter into a bumfight business . </P> <P> Steve and Roger play video games together, get advice from each other and come up with schemes together . For example, he once planned to make a Girls Gone Wild - type video and market it in order to generate money to buy a video game console . In another scheme, Steve and Roger ran away to New York City to make their fortunes, while the rest of the family thought killed when lightning set the family's treehouse on fire . Steve's tendency to inflate his own ego, combined with Roger's easily irritated and vindictive nature, often leads the latter to physically abuse or play a prank on Steve because of a real or perceived slight or insult . Occasionally, Steve gets even, like when he once conned Roger out of $50,000 . Despite their love - hate relationship, Steve considers Roger his best friend, even once intervening to rescue the alien from an abusive relationship . </P> <P> A freshman at Pearl Bailey High School, Steve is a highly capable musician, having taken up the cello to once impress a girl . In a later episode, however, Steve says that he has been playing the cello since he was nine . Steve also plays guitar and sings, which he did as part of a band in the episode "American Dream Factory ." In fact, both of the songs Steve's band rehearses ("Livin' on the Run" and "Sunset Blvd"), were originally recorded by Scott Grimes, who voices Steve . Among Steve's other talents are being able to read Elvish, use Morse code, and communicate with dolphins . </P> <P> While academically skilled, Steve is also quite naïve and not socially savvy . For example, he knows more about the New York Stock Exchange than about prostitution . As a result, he can sometimes be tricked into believing outrageously implausible lies . Roger typically takes advantage of this, especially when he is upset with Steve or when he is simply bored . Once Roger made Steve believe he was not really Stan and Francine's biological child . Another time Roger tricked Steve into believing he was an adolescent wizard, and took him to a drug dealer's house, telling him it was secretly a wizard's school, and the drug lab inside a Potions class . </P>
