It all starts when Khloe visits her momager's office and spots a small, golden dog sculpture on her shelf and asks her mom what it is.
"Those are Jeff Koons," Kris says. Khloe replies that she doesn't know what "a Jeff Koons is."
Kris says matter-of-factly that Koons is "famous for the balloon dog" and tells Khloe that she needs to "go to like an art class."
"Just because I'm not as knowledgeable as you, you shouldn't turn your nose up," Kris' daughter retorts. "You should be like, 'Well Khloe, Jeff Koons is' instead of making me feel less than and uneducated."
Khloe points out in a confessional that Kris hasn't known about art "for years and years" and that she's "just learning" about it.
"You can't art shame people just because they know less than you," Khloe adds. "I'm your f--king daughter and you're art shaming me and it's mean."
The "Revenge Body" star tells her mom that she doesn't "understand why people like to make everyone feel like shit."
"Sorry, it's a Jeff Koons," Kris replies to her. "K-O-O-N-S."
"You didn't even know," Khloe snaps back at her.
