Boys will be boys. Especially with their toys.

Lesson learned for Rob Kardashian who got a real adrenaline rush in the desert today when he flipped his ATV while racing around with Brody Jenner and pals—crashing like Danica Patrick at the Coca-Cola 600. But not to worry, Rob was A-OK.

Turns out, it was something of a feel-good family initiation, as Jenner posted a pic of Rob's topsy-turvy ride to Instagram (later removed) and tweeted, "Big thanks to #articcat #wildcat for letting us thrash today! Glad @robkardashian walked away from this one lol.. now u are officially a Jenner!!"

Minutes before the spill, Rob was all revved up about the prospect of kicking up some dust in a testosterone-fueled desert playdate, tweeting, "Race time and Family time! Me n the Jenner boys" on his Instagram.

It looks like a total gas, even after he flipped the script!

A new season of Keeping Up With the Kardashians premieres June 2 at 9 p.m., only on E!
