Professor Sharp is an older physicist at the university, who shared an office with Professor Roger Abbott. The guys cleaned out Professor Abbott's office after he died and found several notebooks with columns of random numbers in them. They went to see Professor Sharp who shared the office with him to ask about the notebooks and hoped that they were in code about some research project. They turned out to be his diet diary and that Professor Abbott had a theory about limiting his caloric intake would allow him to live forever which was disappointing. Professor Sharp shared the office with him for thirty years and he indicated that where his research led to no major breakthroughs and he consistently had to listen to Professor Abbott's stomach growl, something that he tells the guys they were lucky not to have experienced. Professor Sharp has also never had any major breakthroughs in science. He tells them sarcastically that one gets a rundown apartment like his for winning the Nobel Prize.
Note: Prof. Sharp used to sit at the end of the bar at "Cheers" every week.
