Jeana's always willing to open her home to a guest, even if the guest is a Canadian pageant winner her son met online. Miss Ontario South turns out to be your typical sweet, somewhat slow twenty-something, but Jeana tells the cameras, "I thought for sure it was going to be a pedophile or some 50-year-old-guy."

Jeana's a real prankster.

It was supposed to be a celebration of Jeana's single lady status, but the girls' San Diego vacay nearly went down in flames when Vicki held a hostile limo ride intervention with Jeana over her friend Frankie's rent money. "Frankie is like me," Jeana tells interviewers. "He'd give you the shirt off his back. Vicki would sell it to you." No one stops Jeana from getting her single party on.

What's it like to go on a Gunvalson-Keough family vacation? Let Colton Keough explain: "So you mix my mom, who's mellow, [with] Vicki's crazy, and they're both paranoid. So it's a mellow-crazy paranoid person." A few margaritas, woo hoo's, and touchy comments later, it was clear that Mexico wasn't ready for a Real OC invasion.

You know your mom isn't like other moms when she asks if you want to do a Playboy shoot. The former playmate asked her teenage daughter if she'd be interested in taking some naked pics, but Kara respectfully declined. "My mom is a beautiful lady. I don't think she should pose naked any time soon ... She's in her prime, just not her naked prime." Sorry, mom!

Jeana finds herself in trouble when her boot camp trainer John Ellis makes a surprise house call. His fridge and pantry raid reveals her diet is just as bad as ever, but we can sympathize -- it's not easy parting with all of those delicious processed foods, even delish snacks Trainer John refers to as "instant ass."

Jeana's sarcastic brand of humor doesn't always leave her co-stars smiling. During the fourth season reunion special, Jeana refers to a split second of stupidity as "a Lynne moment," and her harmless dig left Lynne in tears. At least Jeana taught her co-star a lesson: If you want to stay standing for five seasons, you better learn to toughen up.

There's nothing else quite like a Keough road trip. "A lot of yelling and a lot of hitting," explains Kara. "And a lot of curse words and a lot of death threats to my mother." But Jeana's not worried about letting loose on the open road. She happily tells her passengers: "I very rarely crash."

Vicki fondly remembers the day she invited Jeana to boot camp. "I called Jeana, she said, 'Are you F---ing on crack? There's no way I'm working out at 5:30 in the morning!'" But the dynamic duo showed up, whining through each lunge and ab crunch. Vicki also learned the hard way not to accuse her gal pal of cheating workouts. "I have results," Jeana told Vicki. "You look the same." Burn, baby, burn.

If Mexico wasn't ready for Vicki and Jeana, then Vegas definitely wasn't. The ladies are partying harder than freshman sorority girls on the first night of college (with Jeana getting "blackmail pictures" all the while.) One suitor asks Jeana if she's still single. "Why?" asks Jeana. "Is your dad looking for a date?" Oh, don't hit on a Real Housewife unless you actually have game.

After five tumultuous and drama-packed seasons on "The Real Housewives of Orange County," tonight, Jeana Keough says goodbye to her fans and fellow OC wives. Jeana and her one-time partner-in-crime Vicki Gunvalson are the only two original cast members still standing, proving it takes a strong woman (and more than a few strong drinks) to survive five years of Coto de Caza-brand drama.
