In the season 9 episode, New Kidney in Town, Peter becomes addicted to RedBull and is shown to appear on the show The Price is Right, where he spins the wheel so fast that it comes loose and runs over the studio audience. This is followed by Peter saying "Paramedics, come on down!" in a sing-song voice and then performing some kind of spot-run while laughing in a weird manner.
