Well, I suppose it's not completely what I would've expected, but not that bad a list in the end. 
Admittedly, if I'd been the only one making this list, I would've probably put "The Lily-Crested Crown of Clovis I" in the #1 position. You have no idea how many times I've tried to go over lists of certain episodes for trivia games or whatnot, and that one is just impossible for me to think of, no matter what. 
I'm also really shocked by "The Crown of Queen Nzinga" making it to #2, mostly because of the unique details about the Temple Run (only artifact in the Lightning Room, only run ended by a Temple Spirit, one of only three with all three guards in adjacent rooms). I probably would've also put "Sojourner Truth" a bit further from the end and "Scheherazade" a bit closer to it, but I suppose in those cases (and possibly "Clovis I" as well), Nick GaS's airing decisions might've had a subconscious impact on what episodes I remember better. Who can tell? 
Yeah, this is a pretty good list. I would have made some serious adjustments though, had I made this list myself. I agree about "Lily Crested Crown," there is NOTHING memorable about that episode. No wonder people forgot this was even an episode back when Nick Gas wouldn't play it. I would have given the #1 spot to "The Stolen Arm of Shiva." Seriously, do you remember
anything about this episode? I've only seen the full episode twice, and I always forget this is even an episode most of the time.
I agree about Nzinga, I really wish I would have eliminated that one sooner. Aside from the artifact location and the temple guard placement, there really isn't anything exciting. Sojourner Truth and Scheherazade deserve their spots in my opinion. Those episodes have next to nothing memorable about it.
And interesting list there, TRJ. You're right, temple runs and the whole episode itself are two completely different ballparks. I can't wait to do a most memorable episode/temple run list. Though I can tell one of those games have already been started.
