In his appearances on "Seinfeld" (1990), he plays Reilly a wisecracking co-worker of George Costanza who picks on him for stuffing himself with shrimp during a staff meeting. Humiliated, George develops his "the jerk store called" comeback line to use against Reilly. The "jerk store called" became a phrase used in popular media to describe an idiot and the 'Jerk Store Grunt' sound was used in the video game Halo 3 (2007) (VG).
