In this week’s episode, Kim and the gang head to Vegas to celebrate Kim’s birthday. Problem is, Kim needs a serious attitude adjustment and refuses to have fun! Watching her in a bad mood for 22 minutes was just about enough to put us in a bad mood. Luckily, Khloe and Kourtney were there to deliver some hilarious quotes about the situation. We were hard pressed to pick just 10 brilliant quotes from this episode. But we did it — and here they are — the best, most juicy lines from “Diva Las Vegas”!

10. It could be worse. You could be 90.

Kim: Thirty is so old and it freaks me out a little bit.

9.  For once, Scott exercises good judgment.

Scott: I can already feel it. Vegas doesn’t want anything good for me.

8. We wish you would!

Kim: I’m not going to do anything crazy.

7. Do you have a better idea?

Kim: The whole keg stand/college-y thing just seems really stupid to me.

6. Don’t hold back, Khloe.

Khloe (about Kourtney): Favorites, favorites. We all have ‘em.

5. Understatement of the year.

Kim (about Kris): She’s so embarrassing. She needs to act her own age.

4. Things we hope our sister will never say.

Khloe (when Kim doesn’t answer the door): I wonder if she’s masturbating.

3. Things we hope our mother will never say.

Kris (to Kim): Do you have a yeast infection?

2. She’s got a point.

Kourtney: Kim thinks by the time the clock strikes midnight on her birthday she’s going to turn into a little troll in a cave.

1. Everything’s coming up roses.

Kourtney: I told [Kim] yesterday if she could just stick a flower up her vagina so when [she] takes off [her] underwear this will be there. So when a guy comes over and he looks in there he’ll be like, “Oh!”
