Justin Pitt, usually called Mr. Pitt, is Elaine's eccentric boss during Season Six. He is an executive at Doubleday publishing company and hired Elaine to be his assistant solely because she reminded him of Jackie Onassis when they first met. However, he often had her do rather trivial work for him, including spending hours finding the perfect pair of socks, removing salt from his pretzel sticks, and winning a ticket for holding a rope for the Woody Woodpecker balloon Macy's Thanksgiving day parade. He also has the unusual habit of eating Snickers bars with a fork and knife. He was going to put Elaine in his will, claiming she was like a daughter to him. He and Jerry met at the Pharmarcy, but he fires her after he and his attorney suspect Elaine and Jerry are trying to kill him. He shows up in court in "The Finale" to testify against Elaine. Justin Pitt is portrayed by Ian Abercrombie.
- He's very particular about the white socks that he wears, forcing Elaine to spend hours looking for the perfect pair. This mission kept Elaine from going to Atlantic City with Jerry, George and Kramer for the Miss America pageant in "The Chaperone".
- He has an aversion to fountain pens, and ink is forbidden in his office. A fountain pen's explosion was at the core of a scene at the end of “The Gymnast”: Elaine gripped his coat while her hands were covered in ink to get him to stop staring at a Magic Eye poster and go to a meeting, at which the ink had gotten on his upper lip, lending him a resemblance to Hitler, as he emphatically told a meeting of investors that "we will annex Poland by the spring at any cost and our stock will rise high!"
- He eats his Snickers candy bars with a knife and fork, which became the running joke for The Pledge Drive.
- He also seems to have a fondness for Woody Woodpecker, and in "The Mom and Pop Store" got to live out his childhood dream of holding up the Woody balloon at the Macy's Thanksgiving Day Parade.
- Pitt is very wealthy, and lives in an expensive apartment building. This set up the plot of “The Doorman”.
- He was a close friend of Jackie Kennedy Onassis and hires Elaine because he believes she looks like her.
- He is British and speaks with a Received Pronunciation (BBC English) accent.
