Since I got my new iPad, the old one has de facto become Ty's (don't tell him I said that!).  I let him arrange and add/subtract whatever apps he wants.  One day I needed to use it for something, and found that he had put all of his apps into folders (apparently he's a proponent of the "clean screen" school of thought), and these are the folders he created:

Super cool games
Entertainment
Awesome
Exercise games
Games
Pie
Games and more
Funny
Brand new
I never yous
I do not know what these are
Non games
Poket
Pokemon

An interesting look into the mind of a 7-year old.  :)
