Some people might watch "The LYLAS" (9 p.m., WE, TV-14) to laugh at the display of trashy behavior and delusional attitudes. But as we've learned from every "Real Housewives" episode or a "Here Comes Honey Boo Boo" special, a little stupidity goes a long, long way.

The Lylas are a quartet of four singing sisters who just happen to have a famous brother, Bruno Mars. They don't want to be known only for that fact. So, naturally, they talk about it all of the time.

For the record, "The LYLAS" is not a misspelling of the ancient Eric Clapton tune, but the acronym for "Love Ya Like A Sister." If you're going to use "ya" for "you," you might as well be consistent and write "sista" for "sister." But I digress.

Regardless, the Lylas aren't about consistency -- or making much sense at all.

After the tragic death of their mother, the sisters, Jaime, Tiara, Tahiti and Pres-

ley, "honor" her by getting tattoos. Hey, nothing says "grieving" like a trip to the tattoo parlor. They even startle the needle-wielding artist when they ask if he can mix their late mother's ashes into his ink. Sure, why not?

All of this comes after their mother left them with one major, specific request: Don't get tattoos.

Some "honor." Some daughters. Some sisters! Did you hear they have a famous brother?

---Who knew Brooklyn-born Penthouse magazine founder Bob Guccione was a failed painter who studied in Rome for years? Or that his publication scandalized London before dethroning Playboy's Hugh Hefner in the United States? These and other nuggets emerge from the 2013 documentary profile "Filthy Gor geous: The Bob Guccione Story" (11 p.m., Epix).

As "Filthy" shows, Guccione brought a painter's sense of dark and light to his photos. If Playboy models looked like cartoons, Guccione's compositions resembled Old Masters, or scenes from the kinds of European art movies that featured fleeting nudity.

The film makes the most of Guccione's outsized personality, flashy clothes, gold chains and Ron Burgundy-like public

machismo. It's got great period footage and a killer soundtrack.

"Filthy" also explains Guccione's respect for women, a trait instilled in him by his

Sicilian-American mother.

Penthouse was predominantly staffed by female editors, managers and advertising executives in the 1970s. According to one editor, the only publication that was more feminist at that time was Gloria Steinem's Ms. magazine.

---"JFK: The Final Hours" (8 p.m., National Geographic, TV-PG) recalls the last day of John F. Kennedy's life from the point of view of those who encountered him on his fatal trip to Texas. It is narrated by actor Bill Paxton, who as an 8-year-

old boy saw the president address a Fort Worth crowd only hours before the assassination.
