You ever have things go right for you, you're in a competition where you're competing with all that you've got, armed with a good idea and a banana, only to find out that you've been competing in something else the whole time? That happened to David last week, as he turned an all-too-obvious joke into evidence of his false beauty. Meanwhile, Liz is being her usual charming self as six remain in the house.

Everyone wants David to come back... except Liz, who wants Craig to come back. Because she wants to hump him. And... there's the hump right there. Meanwhile, Craig plays the sympathy hoping to get some kudos from the house. 

Clubbing and drinking ensues. Afterwards, Erika and Taylor have a Liz-centered conversation... that she totally walks in on.

Michelle is picking out clothes and shoes for today's activities... which is taking a long time. One suitcase will suffice.

Challenge #4: Change My Score!

Players are going to act as tour guides, being judged on their appearance, enthusiasm, knowledge of Vegas by a real group of tourists. We're going to see how they act when they think no one is watching...

Some fun facts...

- 600,000 people live in Las Vegas... about 1/3 of the population of New York City.
- Las Vegas is the county seat of Clark County.
- No one here has any sort of book learnin'.

The next day... we reveal the secret twist, in that one person (plant) will give a negative review of these players, and they'll have the opportunity, via a tour bus operator (plant), to have their scores changed. More on that later, though. Meanwhile, here's what else we learn from our tour guides.

- The Venetian has a Spanish motif, according to Liz.
- The theme of the MGM Grand is... the Wizard of Oz, according to the clueless tourist.
- The tour starts at the Trop, per the Let's Make a Deal's marquee.
- Bugsy Seagal, Steven's brother, named the Flamingo after his girlfriend.
- Planet Hollywood is famous for its "Miracle Mile"
- Tour guides usually are required to speak.
- The black pyramid looking building is... the Luxor, where Craig buys his cocoa butter.

NOW... will they beauties decide to have their scores changed?

Craig: PASS
Erika: PASS (and she didn't even peek at it)
Liz: BIG FAT FAIL
Amy: PASS
Michelle: PASS
Taylor: PASS

Well, if there was ONE candidate for elimination... seeing that Liz has YET to pass a hidden challenge. I wonder if anyone will breeze on by. Let's get to the results...  The winner of this challenge... TAYLOR! The bottom three: Amy, Michelle, and Liz. Amy? Go back to the couches, we'll see you next week. So it's Michelle vs. Liz in the Final Face-Off.

And they think it's all over. Everyone thinks that Liz is going to coast due to being so darn pretty. Meanwhile, Liz... is in a room by herself. "I'm not even going to go to the Face-Off. I'm going home." Enter Craig, who offers some words of comfort... and tight pants. That lights a spark, now doesn't it?

Let's talk about these two... Liz is a big fat failure. Michelle is not. Michelle has lost every single challenge. Liz... hasn't. Liz has the swag. Michelle... doesn't. This looks like an open-and-shut case, but because they have the time and Vanessa loves to bring this up, here comes the footage from episode 1 with the costumes and the dog.

But just to make sure, let's put up one more test...

THE LAST STRAW: Picture This...

John is having a gland problem... Will the girls be repulsed by his ... schweatiness? Even more so, John thinks that they're celebs. Will they play along? Michelle doesn't on the latter, and gives our John a hug. How nice. Liz... well, we'll see in a moment. Right now, let's go to the Final Face-Off.

Michelle says that she has a lot to learn, and she could lose the growth. Liz thinks that she has the perfect personality, intelligence, and mentality.

... MICHELLE... you're safe. Liz is going home, but before she does, we have one more bit of business... And here's Vanessa with it. And after the requisite footage showing us all the crazy stuff that went down... Liz just walks out.

"I guess we made the right decision."

Guess so. That's a show. Five are left, but who'll survive... MOMZILLA? Stay tuned.
