Bristol Palin and her sister Willow will be switching places with Joan Rivers and her daughter Melissa for an upcoming ep of 'Celebrity Wife Swap' -- even though calling a few of them "celebrities" is questionable and no one involved here is a wife.

They're just picking names out of a hat at this point, right?

In the episode, the Rivers clan will travel to Bristol's home in Wasilla, Alaska, where she lives with her sister Willow. There they will take care of Bristol's 4-year-old son Tripp (and possibly look for Russia). A press release jokes that Melissa will have a hard time "deal[ing] with Tripp's boyish exuberance."

Meanwhile, Bristol and her sis will head to the Rivers' house in Los Angeles to look after Melissa's 12-year-old son Cooper. Even though Cooper can probably fend for himself, Bristol apparently vows to "lighten things up" for him in the home that also serves as the set of three reality shows, one of which is most likely the one they're currently on.

The episode will air June 23 at 8:00 p.m. on ABC. If we're lucky, the original pit bull in lipstick will stop by for a visit while Joan is in town. (Now that would be worth watching.)
