I found this puzzle in an old issue of Science digest, It's one of
my favorites.

There are 3 men living in 3 seperate houses within a fenced in courtyard.
Following a particulary vicious argument over a gardenhose, they made
up their minds never to cross each others paths again.  This seemed
like a good idea at the time (considering the heated debate over gun
control :-) ), however, they all had to go to work at the same time of
the morning.  They settled on this:

Each man was to use the gate directly opposing his house, the man
living in house A had to exit through gate A, the man living in house
B had to exit through gate B, and the man living in house C had to
stumble out through gate C (he didn't take well to mornings).

I'm not sure if this diagram will be readable on other terminals, so
I'll do my best to describe it as well.

This is a square courtyard with house A being in a corner, flush
against the fence.  His exit is diagonally across from
his house (in the far corner).  Houses B and C are to the right and
left of house A set away from the fence (on either arm of
the 90 degree angle formed by house A) and their exits are directly
across from them.

The object is to draw their paths to their respective exits without
their paths crossing.

PS  If it turns out to be too easy, I won't post the answer.  On the 
    other hand, if it turns out to be too difficult, I might not post  
    them anyway !

Only kidding !  :-)
