What was the most significant moment in the history of Ted and Barney's friendship on How I Met Your Mother?

How I Met Your Mother is a popular TV show that ran from 2005 to 2014. Throughout its nine seasons, the show chronicled the lives and adventures of a group of friends in New York City, with a particular focus on the relationship between Ted Mosby and Barney Stinson.

Over the course of the show, Ted and Barney's friendship had its ups and downs. However, one moment stands out as the most significant in their history together: the reveal of Barney's real job.

For much of the show's run, Barney was portrayed as a womanizing, materialistic playboy with no real job to speak of. However, in the eighth season, it was revealed that Barney was actually working for the FBI as part of a long-term sting operation.

When Ted found out about Barney's job, he was shocked and impressed. The reveal not only showed that Barney was capable of more than he had let on, but it also solidified his friendship with Ted. In the end, the revelation of Barney's real job was a turning point for both characters, and it remains one of the most memorable moments in the show's history.
