Smeghead brings up how Movie 43 stole the chin balls joke from this episode and then ponders if Trey Parker and Matt Stone left the film for this reason.
Cartman manipulates his mom into appearing on The Maury Povich Show by saying "Ohhh, I have such a pretty mother, such a wonderful mother." This is a parody of the scene in "The Bad Seed" where the character Rhoda (an 8-year-old serial killing little girl) manipulates her mother into doing her bidding by saying to her "Ohhh, I've got the prettiest mother. I've got the nicest mother."
The boys speak to some "Star Trek" nerds who have pictures of lots of characters on their walls. Also, Maury Povich's ratings man is dressed like Spock and looks like Spock and is looking into a scanner like Spock did on the series.
