At Susan Wornick ’s going-away party at Channel 5 on Friday, station management presented her with a $3,300 check establishing a journalism scholarship fund in her name at Natick High, her alma mater. But the highlight was a slide show imagining what life might have been like had Wornick gone to jail in 1985 (after refusing to name a source, she barely avoided the slammer). For one thing, all her charitable fund-raising would have come from other inmates. “It was hilarious,” Wornick said after the party. Emcee Bob Lobel , Wornick’s ex hubby and BFF, quipped, “Here we go again, me giving her checks.” To which Wornick shot back, “Yeah, but this one I can cash.” On hand to salute Wornick were Tom and Angela Menino, Wyc and Corinne Grousbeck, Tom Stemberg, Mary Richardson, and a host of other pals and colleagues. . . . Treat Williams dined at the Union Oyster House Monday. We hear the actor is in town shooting a pilot for television.
