Friday was yet another nasty day on the market, which prompted Cramer to want to talk about irrationality. Somehow, one of the most boring groups in the market has found a way to start trading in a completely nonsensical way. Burger stocks!
The "Mad Money" host has found that this group is no longer driven by valuations and fundamentals and is instead driven by feelings, whims and portfolio managers' taste preferences.
"I'm addressing this topic because I want you to understand that not everything makes sense at a given time in the market. It's not that you can't comprehend things, it's just that often things are incomprehensible," Cramer said.
What makes Cramer think the burger group is suffering from irrational fever? Symptoms include craziness for burger related IPOs, lack of respect for the high-quality names like Jack in the Box, surprise winners like Red Robin and the way that investors trade in and out of McDonald's.
"If you would have told me six months ago that the hamburger group would become the most emotional and even whimsical cohort in the market, I would have laughed you out of the room. Turns out the joke is on anyone who is trying to apply valuation metrics to this crazy industry," Cramer said.
So, if you are an investor looking for value, then Jack in the Box is the way to go. If you want a potential turnaround, then buy McDonald's. But if you just want a good hamburger—without the stock—then Shake Shack is the way to go.

After Friday's rally in the airline stocks, Cramer thinks this is a fantastic time for investors to trim their portfolios into strength.
"Why? Because the airlines are a hard sell right now, and I don't mean they're difficult to part with," the "Mad Money" host said.
What he meant is that the airline cohort has been falling fast lately, and investors should take advantage of the bounce they saw on Friday.
If you think about it, there really isn't any group that has been able to bounce back quickly from a hammering and come out on the other side as if nothing happened.
Some may say that biotechs and cloud stocks have, but they are both well-below where they were previously.
At the moment, Cramer sees that estimates for airlines are too high, and stocks imply don't bottom ahead of earnings estimate cuts. They bottom after the estimates come down.
Thus, Cramer recommends waiting for the estimate cuts, downgrades and chartists to claim this group is the worst—then jumping in and doing some buying. No matter where they are, Cramer is willing to bet that they will be cheaper than where they are now. Once that happens, Southwest would be the first airline he nabs.
In the Lightning Round, Cramer gave his take on a few caller favorite stocks:
Achillion Pharmaceuticals: "They gave up the upside when they made that deal...We have to be very, very careful. I do not want to own that stock."
Retail Opportunuty Invest Corp: "We are going to wait on the REITs because of all of this Fed rate hike talk. Unless it yields more than 5 percent, we are pulling back."
