- First, this HP Random Pairing Generator gives what seems to be mostly the more mainstream characters. I think it's my favorite pairing/character generator.
- If you like the really rare ones, the St Dymphna's Academy of Magick generator seems to go out of its way to include ALL the characters.
Another idea I've seen is to flip open a book to a random page and pick a phrase, or to hit the "random page" button on Wikipedia. Any others? I'm sure I'm not the only one who'd like a few ideas :)
