Some random man is dressed up in blackface and is impersonating Kanye!

Kim and Kris are extremely uncomfortable, but first they must wait to do their live interview with a German TV host.

What they hear next shocks them:

While the man was trying to be funny by making a reference to a Kanye song, Kris and Kim find his comment to be extremely offensive and they're ready to leave.

Kourtney pops by the new house and is stunned to find that Scott has already moved in. He's lying on a blow-up mattress on the floor!

Scott tells Kourtney that she needs to move past her fear of change because it's holding her back from moving into their dream home.

Kris and Kim are relieved to finally be home tell Khloé all about their awful trip!

While on the plane, some woman started screaming racist remarks at Kim and her baby. It got so bad that the pilot had to come out and talk to the woman!

The experience made Kim extremely uncomfortable, especially since it was the first time she had ever experienced racism.

It's official moving day and Kourtney has finally come to terms with the big move. She admits to Bruce that she isn't the best when it comes to dealing with change, but she has taken the necessary steps in order to make the move easier on herself.

She had exterminators come in to take care of the pest problem, not to mention that the people who bought their old house want to move in ASAP, so she was forced to speed up her moving process.

Inspired by her negative experience in Vienna, Kim decides to start writing a blog to encourage more positivity and acceptance in the world. Now that she's a mother, she doesn't ever want her own children to go through what she experienced.

By writing about her thoughts and feelings, Kim hopes to serve as a positive role model for people everywhere!
