Here's a St. Patrick's Day that Khloé Kardashian will never forget—thanks to her nephew, Mason Disick.
As seen in this Instagram video posted by the E! star on Monday, the little fella took it upon himself to playfully hit his fellow family member on the head with what appears to be a red hat.
"Mason!" Khloé exclaims with a laugh following the 4-year-old's silly smack.
But clearly there were no hard feelings.
"I love being an aunt!!!! #AuntieKoKo," Khloé captioned the clip.

Yep, these two will no doubt continue to grab meals together, much like they did last week when Khloé joined Mason, his dad, Scott Disick, and Bruce Jenner for a bite in Los Angeles.
Meanwhile, on Tuesday, the Keeping Up With the Kardashians star opened up about her impending divorce from Lamar Odom when she phoned in to Australia's 2Day FM "Breakfast With the Stars" radio show.
Speaking to cohosts Mel B, Jules Lund, Sophie Monk and Merrick Watts, the 29-year-old was refreshingly candid, saying, "It's definitely not anything I'm through. I'm going through it, but I'm not through it."
