Jimmy is a friend of Ron Alexander.
While playing billiards at a bar, Jimmy and Ron began discussing the Ghostbusters. Jimmy wasn't as interesting in the business as Ron was. He highlighted the fact they employed nuclear backpacks and didn't see how Ron could get access to their equipment schematics. Once Ron got a working prototype completed, Jimmy expressed his reservations but Ron went on with the test. Suffice to say, it was back to the drawing board.
The next year, Jimmy accompanied Ron to the Firehouse. While Ron relished in finally being hired to the Ghostbusters, Jimmy mused all it took was some prison time. Ron brushed him off and advised him to go back to his car before it was towed.
Jimmy appears to be rather skeptical.
- According to Ron, Jimmy always has bad feelings about things. Hence, Jimmy never had any fun in college.
