It’s still summer-vacation time on the jaunty third-season opener, which finds Malcolm and his rowdy clan cruising on a lake in a houseboat with Stevie and his straitlaced parents, Abe and Kitty Kenarban. Some vacation. The vessel itself is a fright, a weathered heap that Dewey hates from the get-go because ”There’s no TV! There’s no TV! There’s no TV!” An equally distraught Malcolm is shanghaied by Hal for a fishing expedition, leaving lucky Reese the chance to trawl for bikini-clad beauties at a nearby camp. Back on board, the close quarters are slowly driving Abe off the deep end.
