IBM(IBM) - Get Report : Can Watson really move the needle? That was the question Cramer was pondering after visiting the company on last night's show.

While it's true that Watson is only a small part of a very large company, it is a sign that IBM is working hard to offset its ailing legacy businesses with new cloud-based technologies that, one day, could be a big deal.

Watson could become a real "door opener" for IBM's salesforce. If you're an executive at a major company, how could you resist giving Watson's incredible ability to analyze and predict trends a try?

In the case of health care, as traditional medicine surrenders to personalized medicine, Watson's ability to match patients with exactly the medicines they need will soon become essential. After all, only Watson can scan 12 million medical research papers, along with every drug trial currently underway, and provide a comprehensive, unbiased course of treatment.

Cisco Systems(CSCO) - Get Report : Cramer welcomed John Chambers, the outgoing chairman and CEO of Cisco Systems(CSCO) - Get Report , a stock that's risen 10% since Cramer last checked in back in January. Cisco just reported an earnings beat of 1 cent a share on a 5.1% increase in revenue. It is an Action Alerts PLUS holding.

Chambers said he's leaving Cisco in its best position ever for incoming CEO Chuck Robbins, who will be taking the helm on July 26. He said Cisco has evolved from selling boxes to selling outcomes and that strategy is resonating in their public, commercial and enterprise markets.

Chambers noted that there are always new challengers in the technology world, but Cisco has proven that these challengers often come and go in fairly short order. Meanwhile, Cisco is projecting record revenues and earnings for 2015.

When asked about the differences between himself and Robbins, Chambers said that his strengths are in vision and strategy and connecting the dots, while Robbins combines those strengths with the ability to execute on that strategy.

Cramer said that Cisco is one stock that's heading higher.

Entergy(ETR) - Get Report : In his second exclusive interview, Cramer sat down with Leo Denault, chairman and CEO at Entergy, a utility with a 4.5% yield and a stock that's down 15.6% so far this year.

Denault said that the industrial renaissance in America's south and along the Mississippi River continues as industries from chemicals to wood and paper continue to take advantage of Entergy's electricity rates, which are 20% below the national average, to build new plants. That affords Entergy with plenty of growth opportunities to grow its dividend, Denault said.

Denault also commented on the recent transformer fire outside the company's Indian Point nuclear plant in New York. He said the fire was put out quickly and the plant was shut down safely, but it will need to remain offline for several weeks as the transformers are what takes the power from the plant to the grid.

When asked about its new plants under construction, Denault explained the company is working quickly to both replace aging plants as well as increase capacity to meet demand. Most of the new plants are natural gas, as they're the quickest to construct. But Entergy is building both nuclear and solar installations as well.

Cramer continued his recommendation of Entergy.
