Season 5, Episode 8: "The Barber"

Everyone has made the mistake of trying something new when it comes to their hair. Seinfeld went through everyone’s worst nightmare when his not-so-talented barber gave him an awful haircut. Every attempt Jerry made to see a new barber ended in Enzo cutting his hair and swearing revenge after finding out someone else did in fact cut his hair. Elsewhere, George is unsure if he got a job after the interview was cut short and decides the best thing to do is to just go to work. After a week of uncertainty and doing nothing at work, George finds out he indeed got the job.
