Goofs

 * Toward the end of the episode, where Butters comes home from the mall, Stephen Stotch asks his son, "Would you mind telling me why there's Rice-A-Roni in my coffee?!" He illustrates his point by pulling a spoonful of pasta from his coffee mug, but while holding the spoon in his left hand, another reappears in the mug. When he replaces the spoon, there is still only one in the coffee mug.
 * It shows that Butters runs into the room from the right, but when the camera zooms in, it shows him coming from the left.
