Khloe Kardashian and Mason Disick: St. Patty's Day Fun!
Goofing around, the youngest Kardashian sister was laying on the ground being videotaped when the 4-year-old unexpectedly ran up behind her and whacked her with what appears to be a red hat.
Laughing after the fact, Khloe exclaimed, "Mason!" while Kourtney Kardashian's son made a run for it.
Seeming not to be angry in the least bit, the aunt-of-three uploaded the video to her Instagram page, captioning the clip, "I love being an aunt!!!! #AuntieKoKo."
