OK, so you may have seen this puzzle many times before.
Excuse me if it has been posted previously!
I don't remember exactly where I saw it first but the instructions 
go something like this:

GOAL:  Connect the pairs of boxes with the same label. ie [1] with [1],
       [2] with [2], and [3] with [3]. The connections must be made by 
       drawing a continuous line sourcing from one of the boxes
       and terminating at the other.
       By a continuous line I mean anything you can draw WITHOUT
       lifting your pencil.


RULES: 1)Lines connecting different pairs of boxes should not intersect.

       2)No drawing is allowed outside of the big box.


                                 This is the big box.
