I once did a weeks worth of 'debugging/looking at code, trying stuff and testing' before committing my two lines of changed code. About 40 hours of work to produce what would take less than a minute to type. It wasn't even the worst code base I've inherited but it is the worst lines of code per hours worked I've ever had.
