Picross
Have you ever played picross? It's a puzzle-type game that you'd probably enjoy if you like solving sudoku's. For someone like me (obsessive-compulsive with some autism-like tendencies) it's proving to be a great way to absolutely massacre time.
If you google for "picross" you'll find a bunch of online versions of it. I've been busy over at www.wiipicross.com and www.thetimmys.com/flash/picross.
I was going to go into a rant about work, but I just don't have the energy right now. We lost a good one yesterday.. it's hard.
