Love IN PLAIN SIGHT too
Thank you CBS finally a new Criminal Minds
South Park!!!!!!!!!!
Criminal Minds, CSI: NY, MythBusters
In Plain Sight is such an AWESOME show with characters I can get into. USA did good!
Daily Show/Colbert. Won't get South Park until Sunday in Canada.
Can't believe AOP is still on the air. Pretty
dull. Glad In Plain Sight is on tonight, along
with all the ABC lineup, which is the the best
they've ever had. Even ABC repeats are better than
a lot of stuff on the tube.
That picture is really funny. I know he's standing waaaay further back than Thomas Gibson, but Forest Whitaker looks so short! Anyway tonight I'm watching: Bones, Criminal Minds (YAY!), and The Ultimate Fighter.
Nothing
South Park and Fresh Meat 2
Mythbusters and criminal minds. I already saw the new ep of Human Target it was good. I hope this show sticks around.
Criminal Minds and Human Target. Criminal Minds is a must watch this week as it introduces us to the cast of the spin-off starring Forest.
Ugly Betty,ANTM
Wooo! Criminal minds! YAYHOO!
OMG nothing, since no new modern family and the real world is over for now:(
Accidentally on Purpose!!!!!! I'm so glad it's back!
Saw Human Target here Sunday night. A good ep. For something new, I think Bones is aired here tonight...
Nothing tonight.
SouthPark, NBA, Human Target, SVU
