I found some fun sporcles about Lost.
See how many (out of 160) Lost characters you can name in 20 minutes: http://www.sporcle.com/games/AJAX22/lost_characters
See if you can name every Lost episode: http://www.sporcle.com/games/lostepisodes.php
It took me a while, but I can get all the lost episodes named. I can get to like 115 characters before time runs out, too.
Try it for yourself :)
