Although the show has officially ended, a never-before-seen bonus clip from Keeping Up With the Kardashians shows Khloé Kardashian mocking her younger siblings, Kylie and Kendall Jenner, for not hitting the gym. Viewers have seen several scenes showcasing sibling rivalry on Keeping Up With The Kardashians. But this time, Khloé called Kendall a "skinny b**ch," and challenged her to a fight. There is no doubt that Kendall and Kylie have amazing physiques. The reason behind their looks could be genetics, physical enhancements, or working out. Whatever it is, it works for them.

Kylie has established herself as a beauty mogul, and Kendall is a renowned supermodel. Many fans say Kendall has a perfect body, even though she has been accused of photoshopping her pictures on several occasions. Keeping Up With the Kardashians season 20 showcased a battle between the sisters, which settled who is physically the strongest. Kim and Khloé won the volleyball game against Kylie and Kendall. However, Kendall beat her sisters, Khloé and Kourtney, in an obstacle course race by four seconds. Now, many fans do consider Kendall to be more athletic than any other sister.

A bonus KUWTK clip posted by E! shows Khloé mocking the Jenner sisters for their lack of athletic prowess. In the clip, Khloé and Kim Kardashian had lunch with Kendall and mommy Kris Jenner. Khloé told Kendall, "You're not that athletic," and then added, "You're not dedicated like these Kardashian girls." The SKIMS founder Kim, who is popular for hitting the gym early in the morning, supported Khloé's opinion. She added, "Kardashian girls hit the gym heavy."

At that point, Kris interjected, "Kendall was born with abs and biceps. She had little muscles." Khloé agreed to this in a mocking way and said, "That's not fair for us. We have to work for ourselves, daily." She said that Victoria's Secret model Kendall eats burgers and doesn't even do anything. Still, she is skinny. Khloé further added she could beat Kylie and Kendall in a physical challenge "any day of the week." Khloé finished her tirade by saying, "Just because she can climb a rope, just because she's a skinny b*tch, doesn't mean…."

Kendall interrupted Khloé by asking for backup from her mother. She then said she and Kylie aren't afraid of anything. She confidently said, "Me and Kylie, we're down for literally anything. We can do an obstacle course." This is where a genius idea popped into Kris's head, and she announced, "We're going to do the Jenners against the Kardashians! The Kardashian-Jenner Olympics." Kim and Khloé agreed to the challenge. However, all the sisters agreed Kylie might not be ready for it. Khloé said the youngest Keeping Up With The Kardashians star would immediately "throw in the towel." Kim then said she would put money on Khloé and herself and the winners of the competition.
