One group of stocks has been quietly working their way higher in the past year. Believe it or not, there was a stealth bull market for water utilities. Typically investors don't expect huge moves, yet Aqua America is up 35 percent in the past year, and American Water Works is up 57 percent in the same period.
"Those are incredible gains for any kind of a company, they are staggering for a couple of water utilities," Cramer said.
However, while the moves have been amazing, they could be gone. In the case of water stocks, Cramer thinks investors looking to get in are too late for the party as the opportunity is not as great as one once was.
However, utilities could present more opportunity if there was a market-wide sell-off. Dominion is the largest gas and electric utility in the U.S., and has a juicy 3.8 percent yield.
And with the stock close to its highs, Cramer is hoping that market weakness will take the stock down next week to create a buying opportunity.
In February, Dominion announced it was buying Questar for $4.4 billion, and shareholders approved the merger last month. The deal is supposed to be immediately additive to Dominion's earnings once the acquisition closes. To learn more, Cramer spoke with Dominion's chairman and CEO Tom Farrell.
"Looking out long term … we wanted to make sure that we had diversity of geography, so that we could continue to expand our gas infrastructure business once the East gets built up. That's going to take a decade, but with a company like Dominion you need to be thinking out longer than how this quarter is going to go or how this year is going to go. You need to be thinking much longer term," Farrell said.
In the Lightning Round, Cramer gave his take on a few caller favorite stocks:
GW Pharmaceuticals: "I'm saying that it's a big speculative stock, and I do believe that medical marijuana needs to be standardized. That is what GW Pharma has, but boy is it ever speculative."
Novocure: "That should be higher. That stock has come down a lot. Holy cow! We think it's an OK stock. I want to be a buyer of it. I like the CEO."
