I think this episode is great and underated. After trading all his money for "alaskan dollers" Francis is still 2000 miles away from his job in Alaska and gets a ride from a "wannabe psychologist" trucker who makes his journey interesting by forcing him to wear funny props.
Meanwhile Lois goes to a book club because she's fed up of listening to boy noises all the time. She ends up drunk with her friends and they go to "the perfect housewife's" house in an attempt to sabotage her. They end up being chased by the police.
Left at home Hal has to look after Malcolm, Dewey and Reese. His conflicting ideas confuse the boys as he's not sure how to act towards them. You see him talking to various versions of himself with opinions such as "they just need love" to "get the car and go". In the end Hal resorts to taking a bath and not interfering because "you'd only screw it up".
When Lois gets back she has a go at the boys for having fireworks whilst being put under arrest.
