The device Dr. Raully uses to calibrate the memory stimulation device is, in reality, an electric nose hair trimmer.
When Colonel O'Neill is searching the base, he opens a door and finds only a wall. His comment, "damn, cost-cutting" is likely an in-joke to the fact that this is a clip-heavy episode, which are usually produced to save production cost.
First appearance of a CGI Goa'uld symbiote in the series.
The second of several "clip shows" throughout the series run, the first being the penultimate episode of season 1, Politics (1998).
