Ah yes, ferret games.  Here are a quick couple of my favourites:
 
1.  Put woozle or woozles in empty bathtub.  Add ping pong ball.
 
2.  For blase ferrets: place several in large trash bag.  Stick your head
and jump around like a moron yelling Help!  Help!  Ferret in the bag!  This
has been known to pull my ferrets from existential despair into dance
marathon mode.
 
3.  Semi-truck: with ferret's back on carpet, sort of drive him around like
a toy truck, making truck noises if you are not too proud.  Note: some
ferrets love this, some don't like it a bit.
 
Also, I think this is fairly well known, but plastic dryer hoses (tubes?)
make a great toy, cheaper and more flexible than the pricey tube/maze toys
in pet stores.
