Back in the Dark Ages (long before even ARPANET!), I took COBOL, FORTRAN IV, and PERL during the same semester. The same professor taught all three classes. For our major project in each class he essentially gave us the same task, which basically was a simple accounting application for a golf course.
I decided to combine all three assignments into a single solution: PERL for the input/output routines, COBOL for the database, and FORTRAN IV for all maths operations. The professor was only mildly amused, but he did finally give me a 4.0 for all three classes. ?
EDIT: I don't remember the exact number now, but as close as I can recall this took close to 4 thousand punch cards!
