-- "Show me the money!"
As the sisters were taking a walk through Khloe Kardashian's new home, her sister blurted out, "All we have left to take care of is I just need to have my check sent."
Khloe Kardashian appeared caught off guard that her sister wanted money for helping design her home and responded, "The $25,000, you must be out of your mind. Get over yourself."
To which, Kourtney Kardashian said, "Why would you string me along and have me keep working?"
Khloe Kardashian refused to pay and even gave her a little dig about her supposed "work."
"What work? I've done everything with you," Khloe Kardashian fired back.
Kourtney Kardashian said she "spent a lot of time" and needed her money for that.
Finally, Kourtney Kardashian, pregnant with her third child, stormed out and said, "Enjoy living here with your disgusting, cheesy finishes."
The best parts were the solo testimonials on camera.
"I cannot believe that Khloe thought that I was going to help her design her house for free," Kourtney Kardashian said.
"Why would I hire you for $25,000? I thought this was like a fun family activity," Khloe Kardashian said.
