Jim Cramer decided to switch up his research routine on Tuesday. Instead of looking to see what was happening overseas when he woke up at 3:30 a.m., he decided to pretend that the U.S. was an island on its own and focus on corporate data points and companies in the U.S. only to determine how the market would do.

Guess what? It worked!

Simply, Tuesday's market went higher because nothing happened overseas. Greece was quiet; Europe didn't have anything significant and even China had its mouth shut.

That means that investors only had to consider how companies in the United States were doing, and there were so many unexpected gems that they loved.

For instance, Coca-Cola (NYSE: KO) rallied nicely when investors realized it wasn't doing as bad as they thought it was. The real unexpected gem for the day though, was Yelp (NYSE: YELP). This company just disappointed on Friday, and shocked investors when it announced an acquisition and preannounced a revised positive earnings outlook.

The big whammy came on Tuesday, when Apple (NASDAQ: AAPL) announced a partnership with First Solar (NASDAQ: FSLR) to build a $850 million solar energy farm in California.

"First Solar just announced a very interesting deal with Apple that I think is going to send that stock higher," said the "Mad Money" host.

On his birthday, Tuesday, Cramer was reminded of all of the birthdays that were real doozies and lessons learned along the way. But one constant memory is of his father, Pop.

"When you look back at birthdays you tend to reminisce about when they were really special. With old friends. With my mom and the great birthday cakes. With trips to the zoo or ballgame," said Cramer.

Of all the lessons his father taught him, he showed him how much can go right when the retailers do well. That is why when Cramer looks at strong retail numbers from companies like Aeropostale (NYSE: ARO) or L Brands (NYSE: LB), he knows that the ripple effect from these companies is huge.

This could mean more hiring, more merchandise orders and more stores opened ahead. Ultimately, that also means higher stock prices.

Cramer also reflected on retailers such as Hasbro (NASDAQ: HAS) and Mattel (NASDAQ: MAT). These toy makers have tried to keep up over the years, and while they are still major rivals, they are so different.

Hasbro, the maker of Transformers, Nerf, Play-Doh, My Little Pony and superhero action figures like Superman, hit an all-time high on Tuesday after reporting a fabulous quarter on Monday.
