The Superbowl XLV commercial contained clips from many American television shows talking about the game. One of the shows was South Park. Near the end of the commercial, Kyle, Stan, and Butters are riding on a white horse through the streets of South Park. Eric Cartman was behind them, trying to keep up on foot. Stan yells that they cannot miss the commercials. In the center of the screen, a green house has a banner that reads "Superbowl XLV". This clip is not from any episode, meaning that Trey Parker and Matt Stone made the clip specifically for the event (though it does resemble certain scenes from "The New Terrance and Phillip Movie Trailer").
