Who Wants to be a Millionaire (8pm, ABC) - It's Regis's last night of special primetime "Millionaire" shows, but apparently, he's going out with a bang.

True Blood (9pm, HBO) - Sookie, Bill, and Jason (Ryan Kwanten, left) finally return to that upside down, big bowl of mess called Bon Temps. Sookie works on Tara, Bill deals with dreadful Maryann (still can't figure out why people love this character), and Jason tries to help Sam.
Kourtney and Khloe Take Miami (10pm, E!) - This is the one where Khloe gets busted for having drugs (or so E! leads us to believe) at her radio job, and the one where Kourtney hooks up with another girl.
Army Wives (10pm, Lifetime) - Claudia Joy receives a shocking diagnosis after she and Denise get into a fender-bender.
Mad Men (10pm, AMC) - Betty's stroked-out father comes for a visit, and the Drapers must dine out with the stuffy new British boss, Lane Pryce, and his snobby wife. Meanwhile, Peggy (Elisabeth Moss, right) gets a little too personally involved in a campaign at work.
