John Deere (DE) - Get Report : "The next time Wall Street gives up on John Deere, please, please, please remember how management head-faked the analysts" this quarter, Cramer told viewers. Deere's earnings a week ago were so surprising that it makes you wonder how just about everyone missed it.

Before this quarter, shares of Deere were essentially flat for the year. The company delivered a modest top and bottom beat with it last reported in May, but it also lowered forecasts and tempered expectations. Investors took the company at its word.

But shortly after those earnings in May, Deere received an upgrade from a forward-thinking Goldman Sachs (GS) - Get Report , which noted that the time to buy agriculture stocks is when they're at their absolute worst. It turns out, equipment sales were at 30-year lows.

But other than Goldman, no one saw last week's 61-cents-a-share earnings blowout coming. Not only were the earnings terrific, the company's commentary painted a rosy picture for the rest of 2016.

Better still, sales were still sluggish at Deere, and the company delivered on those earnings just by cutting costs and executing perfectly. That means as demand picks up, investors can only expect earnings power to be multiplied.

Dollar General (DG) - Get Report : When is a 17% haircut in stock NOT a buying opportunity? When the stock is Dollar General and it's in free fall.

Cramer said once again the analysts got it wrong and didn't see the weakness in Dollar General and its rival Dollar Tree (DLTR) - Get Report , coming. What went wrong this quarter? Plenty.

First, Dollar General saw increased price competition from a reinvigorated Walmart (WMT) - Get Report . Next, it struggled with price deflation on several of its food items. Third, sales were weaker thanks to changes in federal food stamps that caused 500,000 people to lose eligibility. Finally, as the economy improves, those that can afford to shop elsewhere do.

Cramer said if Dollar General were fighting any one of these issues individually, it could be quantified and priced into its shares. But fighting a multi-front war makes it impossible to value, which means investors need to steer clear until the chaos is over.

Thor Industries (THO) - Get Report : In an exclusive interview, Cramer sat down with Robert Martin, president and CEO of Thor Industries, the luxury RV maker with shares that are up 45% for 2016, trading near all-time highs.

Martin said Airstream remains one of Thor's most iconic brands and production of the identifiable silver trailers continues at record levels and is only becoming more appealing to younger buyers.

When asked about aging demographics, Martin noted there are still five years of Baby Boomers ahead, but Thor continues to gain strength among Millennials as well. It's all about family and the outdoors and getting away, Martin said. Those values span generations.

Turning to his company's structure, Martin noted Thor is a collection of decentralized brands that all compete among themselves. Innovation drives the industry, he added, which is why this model works for Thor. Also helping sales are economic trends including improving employment and increased lending.
