The Brown family will welcome two new additions to the 22-member household, and Kody and his four wives have planned a prank.

According to an ET Online report, Sunday's episode will feature two anthropology students with plans to study the Brown household. Kody Brown's wives have different reactions to the study and the possible addition of the two to their family, with Janelle expressing her worry that the situation would become awkward. "What worries me is that it just becomes really awkward to have someone that close in your space with no down time," Janelle says.

Robyn, on the other hand, is worried about being judged. "I guess the worst case scenario would be if they see our family, and they're like, 'This completely doesn't work.'"

Meanwhile, Christine tries to "set some ground rules" with the two students. Sitting down for a "meet and greet," Christine mentions wanting to "establish some sort of an understanding" before the two could settle in. "This is pretty serious to us because usually when we invite people into our home, they're people we already know," she explains.

The two students will be staying with the household for a few days, Us Weekly reports.

In preparation for the household additions, Kody and his wives have apparently set up a prank for the students. According to Kody, the prank involves his four wives giving him food. To this Janelle adds, "They might think it's a normal thing for us."

In a clip for the show's episode, Kody is seen talking with the students at the dinner table when one wife enters and spoonfeeds him. The wife then shares a laugh with the rest of the wives when she goes back to the kitchen.

The students' reactions are reported to be priceless.

Unfortunately, it doesn't seem like getting to know the two students and playing pranks on them will not be all that the family has to get used to, as apparently one of the students is an atheist.

Earlier this week, the Brown family has also been subject of other news, this time revolving around the dynamics of their household. Kody, who was previously legally married to his first wife, Meri, went through a divorce in order to marry Robyn as part of their family's legal restructuring, shares IB Times.
