Oil and gas stocks have made a strong resurgence this year, but it was the savvy moves of the exploration and production companies that are the true shining stars for Cramer.
The energy sector has now become the best performing group in the S&P 500, which is astounding considering that the price of crude has stalled in the mid-$40s and natural gas remains stuck below $3 per million British thermal units.
Exploration and production companies made the prudent decision to control their own destinies, and have made acquisitions to buy high-quality acreage at low prices.
"These opportunistic oil and gas producers seem to have discovered the secret formula for generating much higher stock prices in this environment," he said.
In particular, Cramer examined the moves of PDC Energy, SM Energy and Pioneer Natural Resources, which have all taken advantage of the energy volatility to scoop up profitable acreage.
At a time when the U.S. is concerned between the relationship between police and communities, products from companies like Taser International have become a mainstay for law enforcement.
Taser is the maker of non-lethal stun-guns and body cameras. Its stock has soared more than 70 percent year-to-date, and the company has also embraced other technologies to help law enforcement, such as audio recorders and evidence management software, to compile data needed by police and prosecutors.
In an interview with Cramer, Taser's CEO Rick Smith explained the significant growth in non-lethal weapons and need for transparency in the current law enforcement environment.
"When we first started doing body cameras 7 or 8 years ago, a lot of people said 'this is 'Big Brother,' people would never wear cameras. Now I can tell you, every police chief you talk to says it's not a matter of if, but when … That's part of what is driving the growth in the business," Smith said.
In the Lightning Round, Cramer gave his take on a few caller-favorite stocks:
PayPal: "My charitable trust ... has been a seller at higher levels. We think it's a good situation, but it has stalled here because the last quarter was just OK. So, I am not going to pound the table and tell you to buy it."
Clayton Williams Energy: "It's a very hot stock, but it just went up $3 again. I think at this point we are just chasing it. We've got to stay away. It's too high."
