Here's what Jim Cramer had to say about some of the stocks that callers offered up during the "Mad Money Lightning Round" Thursday evening:

Global Sources ( GSOL): "I have liked this one. It's a terrific, terrific play on the back portion of the Internet and commerce."

Duke Energy ( DUK): "Scoop some up." Cramer said it might not be as good as Exelon ( EXC) or Consolidated Edison ( ED), but "Duke Energy's good."

IDT ( IDT): "I have not been a fan of the prepaid call business. ... I am gonna steer you away from this one. ... I'm gonna give you to LVLT ( Level 3 Communications ( LVLT))."

Briggs & Stratton ( BGG): "They make the motors that are behind a lot of different engines," including for lawn mowers. "I think this summer's gonna be a lot better for the lawn-mower business. ... Briggs & Stratton is a keeper."

AAR ( AIR): "You know I like AIR." Cramer called it a "well-run aircraft play. ... David Storch, are you there? You know I think you're fabulous. He's the CEO of AIR."

FactSet Research Systems ( FDS): "This stock has had such a move that I have to tell you, the valuation has finally been stretched. ... It's a great company, but it's got about 18% growth, and it's selling at twice that."

Dollar Tree Stores ( DLTR): "It's a winner. ... Dollar Tree is terrific."

Bankrate ( RATE): "Stick with it. This is a really good company. ... Bankrate's a real company, provides a real service. ... I don't want you selling a share."

Nucor ( NUE): "Best-of-breed steel company. ... I like that stock very much. That's a buy."

ValueClick ( VCLK): "They came out yesterday and said it's too big to be acquired. Give me a break. After Aquantive ( AQNT), nothing's too big to be acquired. ... I believe that ValueClick will be acquired. I think it's a great buy right here, down 15% from its high."

Cramer was also bullish on BE Aerospace ( BEAV) and bearish on Archer Daniels Midland ( ADM) and Applebee's ( APPB).

*For all you home-gamers, a 'mon-back opportunity means Cramer would back up the figurative truck and load up on a stock.
