Hank's Bad Hair Day (4x19)

:

Hank's long time barber goes senile, so he turns to Bill, an army barber, for his haircuts. Bill gives him a great haircut, but it turns out that the bill for an army haircut comes to $900. When Hank protests this waste, the army base shuts down its barber unit, and Bill is out of a job.
