Hallmark offers ‘Meet My Mom’

Custom made for Mother’s Day, “Meet My Mom” (9 p.m., Hallmark) begins with gentle music and a doting grandmother (Stefanie Powers, “Hart to Hart”) festooning her front lawn with welcome-home signs and balloons.

But as anyone can expect, the homecoming isn’t perfect. Her daughter (Lori Loughlin, “90210”) and grandson have relocated after a particularly nasty divorce and everybody seems a tad out of place. But this feeling of alienation lasts about five minutes, in time for the son’s class to become pen pals with faraway soldiers.

When one GI happens to be a lonely divorced guy with the time and inclination to throw a baseball around, romance with a single mom can be only a few commercial breaks away.

•Powers and Loughlin aren’t the only female stars of hit shows past on TV tonight. Betty White (“The Golden Girls,” “Mary Tyler Moore”) hosts “Saturday Night Live” (11:30 p.m., NBC).

At 88, White becomes the oldest person to host the long-running series. In 1977, an 80-year-old grandmother named Miskel Spillman won an “Anyone Can Host” contest.

To coincide with White’s “SNL” gig, the WE network will run a marathon of “Golden Girl” episodes today from 3 to 10 p.m. A Mother’s Day “Golden Girls” marathon follows Sunday from 7 a.m. through 1 p.m.

•Tom Selleck returns for the sixth time as the rumpled, therapy-seeking detective in the TV movie “Jesse Stone: No Remorse” (Sunday, 9 p.m., CBS), based on a series of novels by the late Robert B. Parker.

Kathy Baker and Kohl Sudduth are back as Rose and “Suitcase,” his former police colleagues in the small town of Paradise.

Suspended from the force and torn up by a breakup, Jesse has been drinking too much, avoiding calls and having the hardest time programming his new cell phone.

After he’s hired by an old Boston colleague to consult on a serial-murder case, it takes some time for Jesse to get his juices flowing. And of course, he can’t help meddling in Paradise affairs, even though he has been ordered not to.

•Moe departs Springfield on “The Simpsons” (Sunday, 8 p.m., Fox) – but not before writing to Homer, Apu and the Rev. Lovejoy implying that he has run off with one of their wives.

Only the writers of “The Simpsons” could assume that their audience would get a reference to the 1949 movie “A Letter to Three Wives” directed by Joseph Mankiewicz. And only “The Simpson” could make it silly enough to make it funny for viewers not in on the joke.
