"Tommy" Callahan Ill (Chris Farley) business card from Peter Segal's Tommy Boy. When Tommy started working at his family autoparts manufacturing company, his father Thomas "Big Tom" Callahan Jr. (Brian Dennehy) made Tommy his own set of business cards.
The pre-production working title was "Billy the Third: A Mid-western" with the main character "William 'Billy' Callahan III." However, the title was changed to "Tommy Boy" due to Tamra Davis' Billy Madison being in production at the same time. Production created numerous business cards with this name William Callahan III. These cards feature the Callahan logo as well as the company's contact information.
