Corrections & clarifications: A previous version of this story misidentified which Try Guys member has ankylosing spondylitis and the purpose of their tour. Zach Kornfeld has the disease, which is a form of arthritis that primarily affects the spine. The foursome’s Legends of the Internet Tour includes 20 stops for their comedy variety show.

Sometimes it's OK to fail, and there's power (and humor) in that.

Such is the ethos of the Try Guys, comprised of Eugene Lee Yang, Keith Habersberger, Ned Fulmer and Zach Kornfeld, and their new "self-deprecating self-help" book, "The Hidden Power of F*cking Up" (Dey Street, 288 pp.).

The best friends and YouTube stars came to fame with viral videos that showed them trying basically anything, including experiencing labor-pain simulation, having a 9-year-old dress them, doing pottery for the first time and baking bread without a recipe.

The book puts their "try anything" mentality to paper, with all four men delving surprisingly deep to share stories and try new things in their personal lives that aren't just for racking up video views.

They start with their philosophy on trying and failing – or their "failosophy" – arguing that failure is the thing that scares us most but inevitably helps us grow and learn. The Try Guys opened up to USA TODAY about being "four spectacular failures."
