SNL and "Law & Order": Anyone Know Joke Behind "Lisa Pongracic"?

On “Law and Order,” one of the judges who hears cases regularly is named Lisa Pongracic.

I’d forgotten until recently that “Lisa Pongracic” was also the name of Mary Stuart Masterson’s character in the SNL sketch “Lisa Pongracic: Very Pregnant Undercover Cop.”

Is there some staff writer who’s worked for both shows? I know that “SNL” writers often name characters after friends and acquaintances as an in-joke. Anyone know where this particular name came from? (Coincidence seems WAY too unlikely!)

The SNL one is “Lisa Pongrasic”, if that matters.

As of June 2006, there was a Lisa Pongracic (sic) at HBO with the title “VP, Business Affairs.” This per Ross Reports, an industry publication.
