It’s a night of finales on HBO. In addition to “Entourage” (HBO, 10:30 p.m.), ending its run,  “Curb Your Enthusiasm” (HBO, 10 p.m.) ends its eighth season with a finale featuring Michael J. Fox squaring off with Larry David, right.

Then on “True Blood” ((HBO, 9 p.m.) the fourth season ends with a showdown against the witches and a choice for Snookie among Eric and Bill. But there are also some major deaths of characters planned and the return of a couple others after a long absense.

“Celebrity Rehab with Dr. Drew” (VH1, 9 p.m.) also throws a season finale, though it’s never the end for some of these addicts.

On Sunday Night Football (NBC, 8:15 p.m.), it’s Cowboys at Jets. On Sunday night baseball, though, it’s Cubs at Mets (ESPN, 8 p.m.).

“Hillbilly Handfishin’” (Animal Planet, 10 p.m.) isn’t a regional thing. Tonight, a Boston mother and daughter try their hand.

“The Great Food Truck Race” (Food, 9 p.m.) moves into Memphis and contestants are forced to cut out the meat.
