The headline of Steven's newspaper reads "Towlie Ban Lifted," referencing the episode "Osama Bin Laden Has Farty Pants."
The episode concludes with Butters' dad accusing O.J. Simpson, Gary Condit, and the Ramseys of committing the murders for which they were highly suspected. A few years later, John and Patsy Ramsey were acquitted by a jury of their peers, and Matt Stone and Trey Parker have since admitted to regretting their accusations against the Ramsays and Condit.
The way Linda tried to kill Butters is similar to the way Susan Smith confessed to and was convicted of killing her two sons by letting the car they were in roll into a lake in South Carolina in 1994. She also initially tried to blame her sons' disappearance on a person of color.
