While a classic sci-fi trope, the switched minds polt is always a fun chance to see how costars interpret their costars performances. Christopher Judge (Teal'c) really shines both by playing a typically sarcastic and expressive O'Neill as well as highlighting how hard it is to play his usual straightman withoit being overly wooden. Richard Dean Anderson does a passable to fun version of Teal'c and the pair is always fun, but Judge's O'Neill is simply great.
