At one point in the episode, Samantha Carter (
Amanda Tapping) asks Jack O'Neill (
Richard Dean Anderson) how he can remain so calm. He responds with a shrug, "I think in another life I handled dangerous explosives." This is a sly reference to the title role in Anderson's previous series,
"MacGyver" (1985), in which his character, Angus MacGyver, had a background as a bomb disposal expert and frequently used this knowledge to fashion explosives out of ordinary objects or substances.
