Re-watching Stargate, season 1. Daniel Jackson had the worst luck sometimes. Two episodes in a row - first, Thor's Hammer, which could save Sha're and Ska'ara, gets blasted to save Teal'c. Then, in "Torment of Tantalus" he finds the gizmo with All the Knowledge in it, and almost has to yank its parts to get home, after which that planet's stargate sinks and they can't go back. Too bad he didn't think to just grab the whole gizmo, or as much as he could carry, and take it home. At least he's got Ernest's notes.
Poor guy can't catch a break.
