Ian Abercrombie helped bring to life one of TV's most persnickety bosses as "Seinfeld's" Mr. Pitt. From his accidental Hitler speech to the Snickers bar schtick, Mr. Pitt, Elaine's boss on the series, was responsible for many laughs.
When news of his death broke, fans took to Twitter to remember the veteran TV star. In addition to his work on "Seinfeld," Abercrombie lent his voice to "Star Wars: The Clone Wars," and appeared in The WB's short-lived series "Birds of Prey" and Disney's "Wizards of Waverly Place."
Below, see what fans on Twitter had to say about Abercrombie's passing and watch some of his best "Seinfeld" moments.
