In the scene where Roger is taken to Bang Kwang Central Prison the preceding shot outside the prison shows traffic moving on the right hand side of the road, which is factually inaccurate as Thailand drives on the left.
When Roger is on the outside of the space shuttle while in outer space, he breaks the jar he's keeping the two scorpions in, but they survive and crawl into his body. In real life, the scorpions would've frozen up and died instantly.
Roger's opening credits disguise: Kevin Bacon (nose included) from the episode "Four Little Words"
Part of this episode pays an homage to the 1979 Ridley Scott science-fiction thriller movie as Stan Smith wears the same, skimpy outfit that Sigourney Weaver wore as Ripley near the end of the movie within this episode, and the way Roger ambushes the Smiths is similar to the way the alien in Alien ambushed Ripley's fellow crew-members. Stan with a flamethrower is also from the Aliens movie.
The song playing while Roger was working out and while the Smiths were aboard the space ship was "The Sign" by Ace of Base.
