Yes, the episode originally aired on Showtime and they could curse there. (And show full-frontal nudity of Sha're in "Children of the Gods".)

For one, we thought this was the ep that Jack says "Mmmm...Go'uld TV" (but we could be wrong) and also because Jack says clearly "That's bullshit!" in regards to Ska'ara saying 'nothing of the host remains'.

Jack says, "Think it gets Showtime," actually. ;) Did they cut that part out of the Sci-fi version? I'm not sure I've ever watched that episode on Sci-fi.
