Peter "Pete" Hornberger (Scott Adsit) is the "sane" producer of TGS, who often serves as a straight man to the other characters. He works closely with and serves as a trusted friend to Liz, whom, as stated in "Blind Date", he has known for ten years.
In early seasons, Pete is Liz's closest friend at work and the only one she can rely on. Much like Liz, Pete generally plays straight man to the other characters, especially to Liz when she is temporarily pushed over the edge. Prior to his work on TGS, Pete was a skilled archer qualified to compete in the 1980 Summer Olympics, but did not get to go when President Carter decided to boycott the Moscow games. Later episode stated he was a member of the band Loverboy during his teenage years and that his father was a member of the United States Congress.
Pete is married and he has four sons and a daughter. Aside from a brief scene in the pilot where Pete appears at home with one of his sons, the members of his family were unseen characters until the episode "Greenzo". In one episode, Pete reveals that he is afraid of his son Kyle, who is apparently very strong and, in "Black Tie," he spoke with his son Kaleb over the telephone, pretending to be Elmo, in order to encourage his son to "aim your pee-pee at the potty." In "Greenzo", Liz mentions he has three sons named Robert and Jack, and an unnamed one referred to as "that creepy little one who's always rubbing himself on the carpet". In the episode "Anna Howard Shaw Day", his daughter Evelyn is selling cookies for a school fundraiser. His wife Paula is implied to have a rather overbearing personality and Pete often goes to great lengths to make her happy, as in "Up All Night" when he realized that it was Valentine's Day, which also happens to be his wife's birthday. Pete also passed when one of Tracy's entourage expressed interest in him during that episode, showing that he may not always be happy in his marriage but he remains faithful. In the episode "Tracy Does Conan," Pete stated that his wife wishes he was not bald and, in "Black Tie," Pete mentions that they were married in a botanical garden. He lied to his wife about getting a vasectomy, but, as of "The Fighting Irish," she's getting suspicious. Therefore, Pete has asked Liz for the keys to her apartment for "my own safety." He is still living with Liz as of "Greenzo." However, Liz finds out that Pete and Paula are having an "affair" where they sneak around and use her apartment for trysts that include silk scarves and Pop-Tarts; Pete tells her that he and his wife got pregnant almost immediately after they began dating and have never had an exciting romantic/sexual life because of that, so they have found this way to spark their marriage.
With his role of Liz's confidant increasingly filled by Jack Donaghy, Pete played increasingly reduced roles as the series continued, although his marital woes and inability to catch a break were increasingly mined for humor. Jack pities Pete for his aimlessness and unattractive appearance, and occasionally attempts to boost his confidence, beginning by convincing him to wear a wig for a week in "Tracy Does Conan." In "Nothing Left to Lose", Jack is shocked to find out that Pete's only ambition is to remain in his current job. Jack attempts to help Pete by having him make adjustments to his lifestyle, including shaving off what remains of his hair. Unfortunately, it is revealed that his ring of hair was hiding an obscene birthmark that Jack describes as "a swastika made of penises", leading him to be beaten in the street and forced to wear another wig.
When TGS is canceled in Last Lunch, Pete implies repeatedly he is planning to fake his death and escape from his life and family. He succeeds in doing so, setting up a new identity under the name "Dan Silversmith" in Hickory, North Carolina, but is tracked down a year later by his wife Paula and meekly returns to his previous existence.
