<Li> Schmuley "Snot" Lonstein (voiced by Curtis Armstrong)--Steve's best friend with whom he shares a bromance, . Snot is a mustached and acne - covered Jew . He is physically modeled after his voice actor's character's appearance from the movie Revenge of the Nerds, as Dudley "Booger" Dawson . Since Snot was a toddler and throughout much of the series, he had a crush on Hayley; however, in "The Missing Kink", when Hayley finally succumbed to Snot's advances and began to desire him romantically, Snot lost interest in her and deceived her into thinking he was gay, claiming it was the act of pursuing her that aroused him . He speaks Klingon, and can read Quenya . Like Steve, he has a fetish for octogenarian women . His parents are poor, as they could not afford a bar mitzvah celebration, although Steve pays for one in an attempt to apologize when he is falsely accused of theft . His parents have him see a therapist who is implied to engage with him inappropriately and romantically . Steve reveals that his father left Snot's family and may have been abusive towards his mother . He is generally considered Steve's best friend but is quite fickle in this role, having cheated with Steve's girlfriends and pelted him with apples during a period where Steve was in a brace for scoliosis in order to gain social acceptance . When Snot and Steve were younger, they solved mysteries together . He refused to help Steve figure out the mystery, as he quit when "the case of the missing bike horn turned into a double rape homicide". Snot appears to be the least eccentric member of Steve's clique . It is also revealed in the episode "Wiener of our Discontent" that he can somewhat understand Toshi . Toshi exclaims "Oh, my God", and Snot replies "I think you mean' oh, my Godzilla' ." </Li> <Li> Toshi Yoshida (吉田 慧, Yoshida Toshi) (voiced by Daisuke Suzuki)--Steve's Japanese American sansei friend . Though he can understand English perfectly, he always speaks Japanese with subtitles . A running gag is everyone misunderstanding Toshi, assuming he has said something completely different from or opposite to what he has actually said . Toshi studies Russian in order to impress an attractive mail order bride named Svetlana in "Of Ice and Men". He is mischievous, and sometimes, cruel and anti-American . Toshi has expressed the desire to kill Steve as his greatest wish, and he claims to have killed before . Toshi used a katana to kill a group of serial murderers who were chasing the Smith family in "Best Little Horror House in Langley Falls". Toshi has demonstrated that he is the only character outside the Smith family able to see through Roger's disguises, describing him as "the alien in the wig". Toshi has a sister named Akiko, who acts as a translator . Despite his apparent inability to speak English, his mother, father, and sister speak fluent English, (with his mother even mentioning that she does not even know Japanese). Toshi spoke English for the first time in the series in the episode "A Piñata Named Desire" after Snot angrily smacked him and demanded that he learn English . He attempted to say "Eat my balls!", but his heavy accent resulted in it sounding like "Eat my bowls!", which was reflected in the subtitles . He later sang part of "Yah Mo B There" by James Ingram and Michael McDonald on the episode "Home Wrecker". Additionally he briefly spoke English in the episode "Independent Movie" when he asked Steve, Snot, and Barry to leave him alone in a corn field during a soul searching session . </Li> <Li> Barry Robinson (voiced by Eddie Kaye Thomas for the normal voice, Craig Ferguson for the evil voice)--Steve's morbidly obese friend, who has an inarticulate, strident, and sloppy vocal quality . Stan disdains Barry, often impulsively yelling insults at him about his weight without even knowing why . Like Snot, Barry can speak Klingon and seems to be able to read Quenya . Barry apparently has a fetish for Miss Piggy . His borderline mentally retarded and innocent personality is the result of powerful anti-psychotic pills . In "one episode" after stopping his medication regimen, Barry turns into a deranged and demonic mastermind, speaking in a low - pitched voice "like Gary Oldman", framing Steve for the destruction of Stan's beloved commemorative plates . Barry did this in an attempt to replace Steve within his immediate family . Barry's madness grows worse over the episode, culminating with him trying to eliminate everyone that might get between himself and Stan . Steve ultimately tricks Barry into taking his medication, reverting him back to his usual self . This facet of his personality is hinted at when he helps Snot and Toshi beat up a drugged Steve and screams that they should kill Steve's whole family . Barry describes his parents as ignorant and implies that they engage in bondage sex play and smoke pot . Other statements about his parents imply that they abuse him or are negligent, making him sleep in their basement and often forgetting he is their son (and that they even have a son). </Li> <Li> Akiko Yoshida (吉田 暁子, Yoshida Akiko) (voiced by Grey DeLisle in 2009, Grace Park in 2010--present)--Akiko is Toshi's younger sister . She first appears in "American Dream Factory" as a young child with no dialogue when Toshi brings her to audition as a drummer for Steve's Band "The Asstones" but on her next appearance in "Weiner of Our Discontent", she is a teenager, presumably in the same grade as Toshi and Steve . She refereed the hot dog eating contest between Toshi and Steve in the same episode . She speaks perfect English and occasionally translates for Toshi . Akiko dressed as Chun - Li from the video game series Street Fighter for Halloween in "Best Little Horror House in Langley Falls". When Steve develops a crush on Akiko, they are forced to flee from Toshi until Steve convinces him that he is being too possessive of her . Thinking he can open up to Akiko, Steve is stunned when she announces she has a crush on a nine - year - old named Doug because he is a great dancer; however, in a later episode "Spelling Bee My Baby", Akiko developed feelings for Steve and vice versa . </Li>
