We know what you're thinking: How can we possibly pick only five WTF moments for any given Housewives eppy? Admittedly, this is one challenging task, but we managed to narrow it down.

Read on for our WTF picks for The Real Housewives of Atlanta Season 4, Episode 12: "South Africa: Just Like Home."

5. The Luggage

Seriously, it's 10 days! We were expecting one bigger suitcase, a carry-on, and a cosmetics bag each from these ladies, but this was ridiculous. NeNe Leakes and Marlo Hampton were toting at least 15 pieces of luggage apiece... and the rest of the women weren't far behind. Given the cost of paying for extra bags with the airlines these days, their luggage tab must have cost more than most of our rents.

4. Marlo's Etiquette Ramblings

We definitely got to know Marlo a lot better this week and, so far, we're not that impressed. At first, we thought Marlo was attempting a little joke geared toward Phaedra Parks, since she's the self-acclaimed queen of etiquette. But then, Marlo kept the etiquette lessons coming, from everything on how to cross your legs properly to how to pass the damn salt.

Sheree Whitfield put it nicely for us: "How's this for etiquette? Shut. Up!"

3. Marlo's Demands

Let's keep in mind that Marlo basically crashed this vacation. You'd think she'd be grateful to have a place to stay at all, but instead she's demanding that she needs her own bathroom. She just cannot share a bathroom, nope. Oh, and she's also going to need a list of all of the housekeepers on staff, along with their schedules. Wow, rude much?

2. The Weird Voices

No doubt, Marlo and Sheree's blowout will go down in history as one of the craziest, most bizarre catfights Housewives has ever seen. True, no tables were flipped and no one got strangled, but this screamfest had a certain je ne sais quoi that makes it unforgettable. Maybe it was the part at the end when both women took on these inexplicable character voices and made sad faces. Over and over. Surely, this sequence had to be edited, but even just one instance of this behavior is WTF-worthy.

1. The "F" Word

Of course, the most memorable moment of this showdown was how it got started in the first place. When Marlo confronted Sheree about not being invited to her party, Sheree was like, you can come if you want to. Marlo's RSVP? "Anyway, that's why you don't have a man, go and hang with them f***ots with your ugly stupid ass."

Um, what? Oh, hell no.
