Meanwhile, Scott and Kourtney discuss finishing their backyard renovation project because they ultimately want to sell their house and buy a new one. Scott has been annoyed lately because Kourtney frequently disturbs him in his office, which prevents him from getting important work done.

Scott realizes that he can't work from home anymore and voices his concerns to Kourtney:

Instead of listening, Kourtney pops a pimple on Scott's nose. That's the final straw for him!

Back at home, Kim is shocked when she discovers that Kendall's dog has pooped all over the floor in the laundry room!

Kim, not wanting to clean the mess up herself, tricks Kris into going into the room. Kris is definitely not happy about it!

Kris is upset that Kendall is not around to clean up the mess again. She ends up calling Kim a 'piece of s--t' and that's when Kim decides to help.

As usual, Kris is left cleaning up the mess.

Scott has decided to lease a mobile office so Kourtney goes to visit him.

Check out the new digs!

Scott explains to Kourtney that having a mobile office will help him be more productive and make it easier for him to get to appointments around town.

They stop by Khloé's house to pick her up so that she can join them to go see a house that is for sale.

When they arrive at the house. Khloé ends up wanting it for herself and talks about putting in an offer.

Scott is shocked when Kourtney starts talking about putting in extra bunk beds!

Back at the house, Kris and Kendall get into an argument over dog cleaning duties. Will Kris ever get through to Kendall?

Meanwhile, Kim is busy getting glam for a photo shoot. Khloé and Kendall stop by to visit while Kim gets her makeup retouched.

Kendall and Kim get into a heated discussion about the dog situation when Kim takes Kris' side.

Kim's comeback:

While hanging out with Kourtney and Khloé, Kim accuses Khloé of being a bad influence on Kendall and explains how upset Kris is over the way that the two of them have been treating her.

Khloé goes with Kendall to take Blu for a walk and admits she thinks they need to change their bad attitudes and give their mom the respect that she deserves.

Back at home, Scott confronts Kourtney about his mobile office. Kourtney explains that she called the dealership and canceled the lease because Scott already has enough cars that he never drives.

She suggests that he put up a 'No Disturb' sign on the door of his home office so that no one will bother him while he works. While Scott isn't exactly happy about it, he does agree that the van was more of a distraction than anything else.

After getting home, Khloé and Kendall eagerly greet Kris and wrap her in a big hug!

Kris has one question for them:

They explain to their mom that they want to be more appreciative and grateful to her for all the nice things that she does for them.

Later that night, Khloé and Malika are in the car and about to pick Kris up for a 'surprise.'

Khloé gives Kris a quick phone call:

Kris isn't very comfortable with being surprised:

They end up at a nightclub with the rapper The Game and even run into Scott!

Kris ends up having a great time partying at the club with her kids and friends.

In the end, Khloé is reminded of how amazing her mother is:
