If there’s one thing we know for sure, it’s that the Kardashians are cray-cray — in a totally hot, lovable way, of course. This week’s episode of Keeping Up With the Kardashians proved once again how hilarious this family really is. Let’s take a look at this week’s most ridic moments from Keeping Up With the Kardashians, Season 6, Episode 3: “The Former Mrs. Jenner.”

5. Kim and Kourtney do extreme pilates.
This ain’t your normal pilates class, people. Our KDash sisters’ fitness routine was so excruciatingly painful that even Kourtney’s hoo-ha got a workout! Now that’s intense.

4. Kourtney and Khloe ride a Henry the giraffe.
We don’t really know what to say about this one except that, well, it looks kinda fun – and we bet there are a lot of jealous guys out there.

3. Khloe wears a headdress around the house.
Maybe that’s Khloe’s thing, but there are cameras around. Fashion fail!

2. Kris Jenner wants to change her last name back to Kardashian.
Is this woman deluded? She’s been married to Bruce Jenner for 20 years, and she thinks now is the time to reclaim the name of her dearly departed husband and her three (uber-famous) daughters? We think not, woman. Have some respect!

1. Kim gets a butt X-ray.
We know the butt implant rumors are rough, but for reals, Kim? We do admit that watching the actual tush scan go down was hi-freaking-larious. We also hope the X-ray will shut the naysayers down. After all, the proof is in the pictures – even if the fact that they exist is a little strange.
