Lois rushes inside her cabin, and why she left in the first place is beyond me. Because of course she finds Frank in there, slowly and deliberately opening a can of peas. "I'm hungry, Lois," he says blandly, without looking at her. When he gets the top off and dumps a roll of bills into the pan on the stove, he acts all surprised and delighted. "Looky here! Delicious!" he chuckles, pocketing the cash. Lois chases him away from the stove, and he acts like he's looking around for more. There's nothing in the cabinet above the fridge, and as for the canned vegetable cabinet? Nothing in there but empty cans. He got the lot. And wasted the rest of her actual canned goods in the process. Frank makes fun of her for her money-hiding technique (which, he's got a point there), and snarks about the "big spenders down at that Laundromat dump of yours." Hey, don't mock, Frank. You know how much those vending machines charge for one little sheet of Bounce?® Lois gets all friendly and agreeable-like to try and wheedle her money back, but Frank's not about to give back any of Lois's $22,000 (!) in peas without something more valuable in exchange. Much as it pains Lois to admit it, she doesn't have any more. Frank realizes that all this hidden cash means Lois must be some kind of criminal (takes one to know one), but he knows she's not the brains of whatever operation is going on. And then he proves he isn't either, by dictating, "You're going to tell me where it came from. You're going to get me a piece. And you? Are going to make it snappy." He walks out. Since he turns his back on her in the process, I can only assume that he already repossessed Lois's shotgun.
At home, Bill stands before his wives, who are seated around the kitchen table, and announces that his little basement camp-out wasn't planned. He's just got a lot going on with work -- you know, Christmas orders, employee reviews, and no shady acquisitions of gambling companies of any kind. But he's got a plan to make sure it doesn't happen again: he proposes taking each seventh night off from his wives, although by "proposes" he clearly means "you will all go along with this." Leave it to Bill to create a problem for the family and then come up with a solution that only benefits himself.
