Jimmy and Mike haul Lalo's $7 million through the desert in season five, episode eight, "Bagman."

If they had a time machine, Jimmy and Mike would go back to what days. In 1965, when Buffett took over Berkshire Hathaway, Jimmy would invest a portion of Lalo's money.

Buffett probably enjoyed that. During Berkshire Hathaway's annual meeting in 2013, he parodied "Breaking Bad" and gave the finale an A+. A VIP guest on the set of "Better Call Saul" in 2015.

He lost his son, Matty, in 2001. As we've seen from "Breaking Bad" and "Better Call Saul", Mike had a difficult time dealing with the death of his son.

Mike's date change alludes to his refusal to go back in time. A life and career he did not put his loved ones in danger might be a better choice.

Just after the show's title appears on screen, you can see a shot of the mixer at the prison.

In two flashback scenes with Mike and Walter White, Saul asked both men where they would go if they could go back in time.

In another flashback, Jimmy's brother Chuck was revealed to own Wells' "The Time Machine." It describes a future time traveler.

"If you don't like where you're going, there's no shame in changing your path." Jimmy did that in the finale. That took him a while to figure out.

In spite of the fact that "The Time Machine" is never discussed, it is teased throughout the show.
