"Weeds" (9 p.m., Showtime) kicks off its final season, in which we discover if Mary-Louise Parker survived that cliffhanger shooting. "Weeds" may no longer seem as daring as it once did, but the writers and Parker have continued to reinvent the show and keep us guessing. Let's hope it goes out in a blaze of glory and not a puff of smoke.


In the new series "Four Houses" (9 p.m., TLC), competitors go the extra mile during their spring cleaning, in hopes of impressing the others enough to win $10,000 and a chance to be featured in Better Homes & Gardens. Something tells me that homeowners spotlighted on "Hoarders" won't be invited to participate.


Between the Queen's Jubilee and the London Olympics, there's just enough time to squeeze in a history lesson. "Michael Wood's Story of England" (7 p.m., KTCA, Ch. 2) takes you back to the origins of the country and includes a stop in the 14th century, when the country was hit by famine and the Black Death.


Those wanting some patriotic music and fireworks without having to battle the elements and crowds can celebrate the holiday through television. On-air parties include "A Capitol Fourth" (8 p.m., KTCA, Ch. 2), featuring a salute to the U.S. Olympics Team, "Macy's 4th of July Fireworks Spectacular" (8 p.m., KARE, Ch. 11), hosted by original Founding Father Regis Philbin and "Boston Pops Fireworks Spectacular" (9 p.m., WCCO, Ch. 4), which will be a live broadcast.


The Reelz Channel, owned by the Twin Cities' conservative-leaning Hubbard family, owes a lot to a well-known Democratic family. The network celebrates its acquisition of "The Kennedys," which led to a bevy of awards and newfound respect from its competitors, by airing the eight-hour miniseries in its entirety twice, first at 8 a.m. and then at 5 p.m.
