On TV this weekend
America Celebrates July 4th at Ford's Theatre, 9 p.m., ABC Modern Family's Ty Burrell hosts appearances by Kelly Clarkson, Dick Van Dyke, soprano Renee Fleming, George Lopez, Lionel Richie and Robin Roberts, among others. But this is the wrong day!
Flashpoint, 9 p.m., CBS A nutcase radio talk-show host holds a politician hostage to get even for a murder he thinks the guy committed. And that's why President Obama doesn't go on Glenn Beck's show.
SERIES FINALE Miami Medical, 10 p.m., CBS Proctor and Zambrano consider just how far they'd go to save their patients. Not far, as this is the last episode ever.
SEASON FINALE Merlin, 10 p.m., SyFy Maybe Merlin will resurrect Miami Medical as this season's final magic trick. Nope, he's saving that for the Great Dragon.
The Tour de France, 11:30 a.m., Versus Maybe Lance Armstrong is hoping all the other racers are going to implode like the French national soccer team did at the World Cup. Otherwise, we wish he'd stay retired.
Dolly Celebrates 25 Years of Dollywood, 8 p.m., Hallmark Kenny Rogers, Billy Ray Cyrus and his kid Miley stop by to celebrate a quarter-century of the most popular Southern tour stop after Graceland. Of course, we all know Dolly will live forever.
SERIES FINALE Three Rivers, 8 p.m., CBS There would be tension in tonight's episode, in which Andy moves a patient to the top of a kidney donor list, but we'll never find out what happens anyway, so who cares?
A Capitol Fourth on PBS, 8 p.m., PBS D.C. whoops it up with Darius Rucker.
Macy's 4th of July Fireworks Spectacular, 9 p.m., NBC New York City parties with Justin Bieber.
Boston Pops Fireworks Spectacular, 10 p.m., CBS Beantown gets down with Toby Keith.
Bridezillas, 9 p.m., WEtv And since ABC had their show on Friday for some reason, we suggest checking out the 100th episode of entitled crybabies wasting money on a forgettable event that matters to no one but themselves. How much more American can you get than that?
