My Mom was the best at coming up with games to keep us entertained as kids.  Most of the games she came up with weren't really games and just crap she threw together to keep us busy.  Like the super fun "Fishing for Cats".  My Mom would open the back to our old VW Vanagon parked in the driveway and throw me and my brother in the back.  She would then give us fishing poles with cat toys tied to the end of them.  She would then call our cats over and have me and the brother try to "fish for cats" all afternoon.   And to be honest I had a blast!!!!
