This is the day: the day Arnold Shapiro, the defense attorney for O. J. Simpson, is expected to enter a motion to suppress certain evidence in the case, evidence which may or may not be vital to the prosecution's case. Coverage of the day's preliminary hearing is scheduled to begin at noon, with Court TV, CNN and, most likely, all of the major networks in attendance.
* "Sister, Sister" (8:30-9 p.m., WJZ, Channel 13) -- "The Parent Trap" redux: In this first-run episode, the twins try to get their respective guardians to fall in love. Tim Reid, Jackee Harry star and make this sitcom worth watching, despite its predictability. ABC.
* "Tales From the Crypt" (9-10 p.m., WTTG, Channel 5) -- Two of the wildest "Crypt" tales are shown in tandem tonight. In the first one, Lea Thompson plays a prostitute who trades her soft beauty for hard cash; in the second, Demi Moore plays a gold digger who marries a disgusting fat man (played by Jeffrey Tambor with gusto) on the advice of a fortune teller. Fox.
* "NYPD Blue" (10-11 p.m., WJZ, Channel 13) -- The closer it gets to the end of last season's run of "NYPD Blue" episodes, the more satisfying it gets. The show really hit its second wind with the romantic subplot about Sipowicz (Dennis Franz) and Costas (Sharon Lawrence), which is one of the things explored in this repeat episode. ABC.
* "World Cup Soccer: Italy vs. Nigeria" (12:55 p.m.-conclusion, ESPN) -- Today's two games complete the first full batch of single-elimination matches, winnowing the field from 16 to eight teams. Italy began 1994 World Cup play by losing to Ireland, then recovering by beating Norway and tying Mexico. Nigeria, on the other hand, began by beating Bulgaria, then lost to Argentina and beat Greece. In their respective contests, Italy scored two goals and allowed two, while Nigeria scored six goals and allowed two.
* "World Cup Soccer: Mexico vs. Bulgaria" (4:35 p.m.-conclusion, ESPN) -- Mexico's record is like Italy's: loss, win, tie. Bulgaria's is loss, win, win, with six goals scored in its final two games. If Bulgaria maintains that pace, it ought to beat Mexico -- thereby surprising a lot of soccer fans.
* "Mrs. Piggle-Wiggle" (7:30-8 p.m., SHO) -- Shelley Duvall, the executive producer of this series, guest stars tonight as well, playing Potsi Piggle-Wiggle, the daughter of Jean Stapleton's title character. And if Potsi is visiting, can Ralph Malph be far behind?
