One stock that is quickly closing in on an all-time high is Thermo Fisher Scientific, the No. 1 player in the life-science tools business. It creates the lab equipment needed to conduct science and also has a food safety business, diagnostics division and a genomics platform.
Thermo Fisher reported a strong top- and bottom-line beat at the end of April, with higher-than-anticipated full-year guidance — yet the stock barely budged. That was a signal to Cramer that the stock deserves to go even higher.
He spoke with Thermo Fisher CEO Marc Casper, who said the company has partnered with the CDC and authorities in Brazil to develop a test for the Zika virus.
"I think there is so much great research going in the field … I am very encouraged," Casper said.
And then there was CONSOL Energy, which rebounded so hard it took Cramer's breath away.
The company produces both coal and natural gas, two commodities that were crushed from the summer of 2014 until this January. Thus, the company lost more than 90 percent of its value over the same period.
So, is this rebound the real deal?
While Cramer acknowledged that the management at CONSOL have done an amazing job guiding the company through a difficult time, unfortunately the time to buy the stock was four months ago, not now.
"At this point, I think you just need to acknowledge that you have missed the move, and let it go," Cramer said.
In the Lightning Round, Cramer gave his take on a few caller-favorite stocks:
Taser International: "I have liked Taser for ages, and I reiterate that I still like it. I know it flew and came back down, but I think it's a good stock."
Communications Sales & Leasing: "It's got too high of a yield. It makes me want to worry that it shouldn't be a red-flag situation. They shouldn't be that big. If the company wants to come on and talk about it, that's fine. But it's not my cup of tea."
