The near indecipherable and much-debated lyrics to the theme song are: "Hey smiling strange, you're looking happily deranged (Can you settle to shoot me,) and have you picked your target yet Hey Sandy...ai yai yai yai... Does your dog bite (yai yai yai) , Hey Sandy Four feet Away, end of speech its the end of the day We was only funning, but guiltily I thought... You had it comin', Hey Sandy, Don't Ya Talk Back, Hey Sandy." The line in parenthesis above has never been revealed by the band members, and "Can you settle to shoot me?" is only one of several interpretations.
The idea for Pete and Pete's mom having a metal plate in her head came from the story of baseball player and coach Don Zimmer who had to have a metal plate put in his head after receiving a blow to the head by a ball in the 1950's.
According to one of the show's creators, the show was originally going to be about a boy named Pete and his dog named Pete, but they changed the dog to a younger brother when they realized a dog "wasn't exciting enough."
The names of the slushies that the Petes, and the baseball team they belong to, drink are all named after Biblical figures. Flavors mentioned include Grape Judas, Lime Balthazar and the addictive Orange Lazarus.
According to Danny Tamberelli, Little Pete's famous arm tattoo, Petunia, was achieved with an adhesive patch. However, when supplies of the stick-on began to dwindle, they advised Tamberelli to protect the adhesive from water during shooting periods. Eventually, the producers began applying the tattoo with a stencil.
