Mike's busy hosing down his Nissan 5.6 SE King Cab Titan truck with 14 MPG city/18 MPG highway, 32 valve engine, front seatbelt height adjusters, electronic brake force distribution, and radio antenna, when he notices that Julie and Susan are loading up Karl's 'Stang with boxes. He heads over to find out what's what. Susan sheepishly reveals that they're busy moving. Karl jack-in-the-boxes out of the RV, and yells with ferocious glee, "HEY! IT'S THE PLUMBER! You come over to help Suzy move into her new house?" Total manic episode! Mike is confused. Susan is embarrassed. Karl is insane: "You mean she didn't tell you? Oh, I bought a place for my girls." Mike is disappointed. So much for Susan's plans to "go it alone"; those lasted, what, a week? Susan hastens to explain that Karl won't actually be living with them, plus Mike was only offering a single room, while this is a whole house! (Yeah, Susan comes off as unnecessarily mercenary in this scene.) Mike gets in Karl's face and hisses that the only reason Karl bought the house is because he saw Mike buy the ring, and Karl "just had to cut [Mike] off." I'm actually kind of impressed by how easily Mike read this situation. Susan, predictably, goes all goo-goo over Mike's utterance of the word "ring," meanwhile Karl starts shoving Mike with one of Susan's moving boxes. Susan: "Mike, about that ring..." Mike tells Susan, "Not now," and then tells Karl to put down the box. Karl obliges by tipping all the box's contents (pots and ice cube trays, mostly) on top of Mike's head. They tussle on the grass for a few second, ridiculous Susan slapping at them with a spatula, what? Then Karl throws a little metal thing (which later is revealed to be a "salad shooter," which I actually had to look up: for the benefit any other kitchen-ignorants out there, it's a device that automatically slices up, like, cucumbers and radishes and pelts them into a salad bowl) at Mike's mouth, and Mike retorts with a mighty punch to Karl's face, and Julie and Susan fly to Karl's side. Mike pats at his tin-damaged mouth and watches forlornly as Susan and Julie flutter over Karl. Susan gives Mike an exasperated look, and he slowly sways his way back into his house like a groundhog depressed by six more weeks of winter. Mike may have been provoked, but I'm not sure that a fistfight with the bio-dad right in front of the daughter is the very best way to make a good impression? And by the defeated look on Mike's face, I think he knows it. Then again, it isn't exactly the first time Mike's flown off the handle and belted a guy in front of Susan's house. It isn't even the second time.
