Kenny encourages Shel to be more spontaneous -and Shel foolishly takes his advice. Meanwhile, Dave and Beth's hanky-panky in the car sends them straight to traffic school. Trying to embrace the ability to live impulsively, Kenny convinces Shel to go on a last minute cruise and Shel ends up married by the time the boat docks. Arriving back from the cruise married, Shel is distraught when he hears from his new wife's attorney, fearing that she may take him to the cleaners. Meanwhile, Dave and Beth end up at a very strict traffic school, where they are cited for a ""moving violation"" of an intimate nature in their car.
