Critic's corner

Frank TV 11 p.m., TBS
Tina Fey's Sarah Palin and Josh Brolin's George W. Bush have drawn attention to the art of the impressionist and how good impressions can really alter public perception. Impressionist Frank Caliendo shows how mediocre impressions can have no impact at all. Caliendo is back with new episodes of his sketch series, in time to deliver John McCain, Al Gore, Jack Nicholson (above), and Sean Connery.

House 8 p.m., Channel 25
Did we truly doubt that House (Hugh Laurie, above) and Wilson would reunite? No. But the bromantic drama between the two buddies was distracting for a few weeks. Tonight, the attention turns to Cuddy, who, like Liz Lemon on "30 Rock," would like to adopt a child as a single mother. Hats off, as always, to Lisa Edelstein, who makes Cuddy into one of TV's most likable enablers.

Dr. G: Medical Examiner 10 p.m., TLC
Nope, no relation.

Scream Queens 8 p.m., VH1

It's the Great Pumpkin, Charlie Brown 8 p.m., Channel 5
Linus for president.

Dirty Jobs 9 p.m., Discovery Channel
Catching leeches. Can't be worse than catching crabs.

Sunset Blvd. 8 p.m., TCM
We are big. It's the parchment that got small.
