I thought this was a good idea for a thread as I'm always trying to remember what episode something happened in.
The basic idea is you post here if you're trying to figure out what episode featured a specific scene. For example: "Which episode did Booth say 'I'm with Bones Cam, all the way'?" Someone would answer "The Boy in the Shroud." It can also be used if you're trying to find a scene for a video or something and need something to go with the lyrics. Like "Where can I find a clip of blinding white lights?" (I actually need the answer to that, so if anyone knows, feel free to answer.)
Hopefully there isn't anything like this up already.
