I just finished Portal 2 and found the facts by Core 3, the "fact" core, quite humorous and informative (I don't believe him). Since time was short, I couldn't listen to all the facts he might say.

Does anyone have a collection of all the facts Core 3 can say?

All the facts can be found in the subtitles file at \steamapps\common\portal 2\portal2\resource\subtitles_english.txt (or _czech, _danish...). Open it up and search for bits of what you remember, e.g. "dental".
