The Serpent's Lair (3) - S2-E1
Continuity mistake: When Daniel is shot by a Jaffa staff weapon, the hole in his jacket is very visible. When Daniel comes out healed from the sarcophagus, it has also mended his jacket, but it's shown in other episodes that it doesn't repair clothing.
Chosen answer: Report 30185 is a joke report referring to the time when SG-1 go back in time to 1969 in the episode '1969'. The joke is that Colonel O'Neil knocked up a hippie and made sure Mitchel was taken care of throughout his life, like how he got into the 302 program while his buddy, a better pilot, did not.
