Whew! This family’s drama keeps gettin’ deeper. Tonight’s episode of Keeping up With the Kardashians tackles two main issues: Kim’s butt and Kris’ vanity. Both equality important matters. (We’re kidding, by the way.)

The Kardashian family hits a Redbook red carpet event to celebrate their Mother's Day cover issue. Momager Kris Jenner is, naturally, hoggin’ the limelight. During one interview, the reporter calls her Kris Kardashian which brings up an important question in Kris’ warped mind: Should she change her last name back to Kardashian?

Now it’s back to the KDash sisters. Kourtney calls Kim to tell her there’s yet another butt rumor make its rounds through the Interwebz. This time gossip bloggers are claiming one of Kim’s alleged butt implants exploded on a flight to Las Vegas! Kim is visibly upset that people still think her ginormous behind is fake. When she arrives at Khloe and Lamar’s humble abode, the trio Google the rumor and, shockingly, Kim-the-Drama-Queen isn’t devastated. She laughs instead! After all, who would really believe such a ridic story about Kim’s badonkadonk? Ever the jokester, Khloe suggests a surefire way to get the tabloids to quit talking about Kim’s tush: a butt X-ray. Uh, duh! Why didn’t anybody else think of that, like, four years ago?

Flash forward to Kris, Kim, and Kendall enjoying a nice family walk together in the middle of the afternoon. How normal – besides the cameras, papparazzi, and the fact that normal people work real jobs during the middle of the day. However, this sunny little stroll is the perfect place for Kris to drop the “Should I change my name?” bomb on her kids. Kris insists the surname switcharoo would just help to grow the brand. It definitely has nothing to do with the fact that she wants to milk the famous last name for all its worth — not at all! Needless to say, Kim and Kendall are both appalled by Kris’ ridiculous notion that it’s okay to change her name back to her deceased husband’s, when she’s been married to her current one for 20 years. We concur. What is wrong with this woman? We’ve said it once and we’ll say it again: “Poor Bruce!”

And there we have it, the tone of the episode is set. Kim’s out to prove her behind’s the real deal and Mama Kris is all about faking her name. Maybe those two aren’t so alike after all?

Next up, Khloe and Kourtney are just chillin’ at Khlomar’s place, where Khloe is – naturally – wearing a ridiculous feather headdress. We love ya Khlo, but your choice in headwear is mildly questionable. Bad accessories aside, the sisters ring up the third KDash, Kim, to try to convince her to get the butt X-ray. Kim sounds annoyed that her sisters are acting like they don’t believe her badonkadonk is legit, but she agrees to get the thing done anyway.  In celebration, Khloe (headdress included) starts to play make out with Henry the blow-up giraffe from her New York adventuresr. Then, she and Kourtney ride him out of the kitchen. Now, that’s hot.

So, back to Kris Kardashian Jenner. Kris’ husband Bruce pops up to chat with Kris about his wife’s potential name change. When he confronts her about it, Kris insists it’s “only for the brand.” Poor Bruce tells the camera with his puppy dog eyes that his name used to be the big one. He leaves the room pissed off, but not before getting one little jab in and saying, “Bye Mrs. Kardashian.” Oh, snap.

The moniker mayhem continues when Bruce takes Khloe out to practice her golf swing and the subject of Kris’ name change comes up. At first Khloe thinks the whole thing is a joke, but once she realizes it’s not, she’s p.o.’ed. She calls her mom a fame whore (among other things), which we totally love. But Khloe brings up an important point and questions Bruce’s docile reaction to surname switch. Khloe encourages her stepdad grow a pair and stand up to her mom. Um, yeah. ‘Bout time. (Or maybe 20 years too late...)

But since we all know that won’t happen, Khloe decides to take matters into her own hands. She shows up at her Mom’s house livid. The no-nonsense Khloe calls her mom out on her famewhoring ways. She points out that before the Kardashians became a household name, Kris proudly displayed Bruce’s jerseys and Olympic medals. Now her office has turned into a shrine to her famous daughters. And what are those we see? Real tears start falling from Kris Jenner’s eyes. We think Khloe's speech may have made an impact!

But forget all that for a minute while we watch Kim tackle a much more serious issue: her butt X-ray. Yes, fans, it’s happening. Kim looks her family physician straight in the face and says she needs an X-ray to prove her butt is real. Who wants to bet that’s the only time the doctor has ever gotten that request? Just to have a point of comparison, the girls also decide to X-ray Kourtney’s breast implants. The results? Kim’s. Butt. Is. Real. No if’s, and’s or butt’s about it.

Fast forward to the weekly dinner at the Kardashian Jenner house where Kim and Khloe make the big announcement about Kim’s junk. Khloe then puts the au naturale booty pics on her blog to show the world that this booty is all Kim, all the time.  But the excitement of the girls’ newst doesn’t last long. Always one to steal someone else’s thunder, Kris decides to make her own very important announcement. Not only does she still lurve hubby Bruce, she also loves his last name —so much so that she’s decided to keep it. How sweet? She also has a little prezzie for the family portrait hallway: an adorb black-and-white print of Bruce lookin’ pretty fly. In short: Everybody’s happy and we’re happy.
