The fifth season premieres with Jim sneaking off to a Cubs game with Kyle instead of taking him to his first day of kindergarten.

Out-of-shape Jim enters a 10K marathon to teach Kyle, who wants to quit basketball, a lesson about not being a quitter -- but he cheats to get first to the finish line.

Jim realizes that Cheryl has been spoiling their son Kyle for way too long, so he decides to make him a man by teaching him how to throw a perfect punch in self defense. However, things get out of control when little Kyle gets suspended for repeatedly hitting the school bully.
