Their spring break road trip by RV will take an interesting turn when Kody Brown and family meet another polygamist family and participate in a Passover Seder with them on an all-new episode of Sister Wives.

Tempers Flare on Brown Family Road Trip?

The famous family has been travelling across the country together in a set of RV's, and now they will meet with the Richards family--and will experience a proper Jewish seder for the first time--and based on what Kody says about the experience in a preview clip for the episode, the family appears to enjoy the experience, as Kody later explains what he understands the Seder to be about, and also reveals a hidden talent.

"I can say two or three blessings in Hebrew," he admits in a preview clip for the Sunday, July 13 episode. "That's all. A friend of mine who's a Jew, wrote these blessings down for me and I just put them to memory. The reason that I learned these Hebrew blessings was because it would be funner to do these blessings in Hebrew. I just thought it'd be really cool."

He also explains the history of the plagues on Egypt and their role in the Seder--but can't resist adding his own modern twist to the classic religious tale.

"If it was in this generation I'm sure that God would have been more creative and brought zombies," he says after talking about the plague where Egyptian women would find their first-born child dead if the Jews were not freed.

While Kody reminisces about the Seder however, one of his wives, Christine, remarked how much the patriarch of the Richards family, Nathaniel, reminded her of a young Kody when their family was beginning to start out.

"Nathaniel is just 33-years-old and he reminds me a lot like you when you were that age," she says to Kody in the clip. "They were very similar in that they had all these young kids and that they were just trying to do what they felt was right."
