The early screening of Mentalist (4pm Pacific time) was not on today (likely due to the football game). The earliest next screening I know of is at 7pm Pacific time (in 40 min). It should be available about an hour after that when someone uploads it. Unfortunately this is 10pm eastern time and you can probably just watch it then.

If you can't see it then, try http://putlockertvshows.me/watch/the-mentalist/ shortly after 8pm Pacific (about 1hr 40min from now).
