Moebius is the episode at the end of season 8 where SG-1 goes back in time(in the puddle jumper time machine) to steal Ra's ZPM...they screw up the time line, and we go to episode part 2 where Sam and Daniel are dorks, and never involved in Stargate program(in fact we naver even found the gate)...Daniel gets goa'ulded, and Teal'c kills him...then they travel back to where they went the first time(Egypt 5000 years ago) to start a rebelion(again)...they save the world again, fix the timel line and everyone is happy...
Its a fun episode to watch the first time, as Sam and Daniel appear as "nerdy" versions of themselves(alternate time line selves)..
