For one time only Feb. 20, NBC's freshman comedy-drama "Ed" will replace "Dateline NBC" Tuesday at 10. The same episode will air the next night in the show's regular 8 p.m. Wednesday time slot.
In the episode, John Goodman guest stars as Big Rudy, the former owner of Stuckeybowl who returns to town to reclaim the bowling alley.
NBC Entertainment president Jeff Zucker said the double run of "Ed" will give the series added exposure without disrupting the show for viewers who have grown accustomed to watching it on Wednesdays.

ONLINE DATING: Janet Cleversy, a paralegal with Pietragallo, Bosick & Gordon, will be featured in a segment of ABC's "PrimeTime Thursday" (10 p.m. tomorrow on WTAE) about online dating services.
Cleversy, 38, said a "PrimeTime" crew spent four days following her in Pittsburgh and going on two dates with her.
"Neither one of them were too positive," she said.
Cleversy, who lives in Whitehall, said producers for the newsmagazine selected her from the matchmaker.com Web page, where she's had an ad for a little more than two years.
In addition to being taped going about daily life in Pittsburgh, Cleversy was flown to New York for an on-camera interview.
