Sure, but you never know if this next bug is another fix it in 1 hour, or it will take months to figure out. I have had a few "The is not spelled 'Teh'" bugs that it takes longer to find the code in question with grep than to fix, but most are a not that obvious and so you don't know if there are 2 hours left or not until 2 hours latter when you know you found something or are still looking. (or unless you think you fixed it and the time to verify the test is about 2 hours, but then only if your fix worked)
