- “You're Fireeeeeeeeeeeed!”
- ―Costington's catchphrase
Many a Springfielder has worked for him. He usually says Fireeeeeed! or Hireeeeed! when he wants to fire or hire someone, and sounds like he's yelling underwater when he does so. Homer has worked for him on three occasions: as the Thanksgiving Day Parade Santa Claus, as a mattress salesman, and as a model for a leading brand of jeans. He has also employed the The Yes Guy and Gil.
Behind the laughter
Costington is one of the few characters in the show who has eyebrows.
