Hank and Phoebe think the house has been robbed when they return home and discover the furniture missing, but Max admits he hid everything and forces them to earn their belongings back before Barb discovers the truth. (imdb.com)

This was one strange episode of the Thundermans. Barb decides she is going shoe shopping. Max skips out so he can assumably go play with his band; Phoebe and Hank beg off so that they can do some extra super hero training.
Barb, Nora, Billy and Chloe end up at Splatburger, which is having a promotion to see who can be in the new Southwestern Beef commercial. All they need to do is stand with their hands on cacti and outlast Raul, professional commercial guy. Of course, Raul is Mrs. Won’s favorite, so she does everything to make sure he wins and they lose. But when he inadvertantly takes his hand off the cacti, its game on for Barb, Nora and Billy. When they see Chloe with a massive pile of food she has ordered, they take their hands off the cacti at the same time, so they effectively all win. They are portrayed in the commercial as pigs, scarfing down on the new burger. It was just weird.
Meanwhile, when Hank and Phoebe come home from the movies (not superhero training), they find that all of the furniture (including the lamps) have been stolen. They are equally surprised to find out that Max was behind it (I’m not exactly sure what his motivation is, but I would bet that, based on how the episode ends, he’s jealous of Hank and Phoebe spending so much time together). Max orders that Phoebe and Hank become his servants. Max’s original intent was to sell the furniture to our good friend Chainsaw – there’s some convulated tale about how Chainsaw left the money outside Colosso’s window and Hank ripped it up and Chainsaw took all of the furniture to outfit his new coffeehouse. It doesn’t make much sense.
In the end, there’s some insanity about a popcorn tossing event and a bet as to whoever wins either gets the furniture or the house. The Thundermans win and keep their house.
That’s not the most compelling part of the story. Phoebe was right – Max is jealous of the relationship between her and Hank. I would have liked to see a stronger plot to expose that jealously. But Hank and Max work together at the end, and apparently, Max’s contributions to the family are validated.
