In [City] Tonight

Here's a thought I had. When Metallica play "Seek & Destroy" in concert, James Hetfield changes the lyrics to include the name of the city. This is where he does it in the video below: https://youtu.be/RNy2Nel4MeA?t=61 - "Scanning the scene in [name of city] tonight" are the lyrics he changes.

Here's another place where he does it: https://youtu.be/XnUn9FkNp_4?t=54, but here's one place where he doesn't do it: https://youtu.be/M8nZaeyLpc8?t=88

What if there was a video that had just that line in the cities where he changes the lyrics to the name of the city? It would only be going through 749,000 results on Youtube:

Let's say that it takes one minute to find the precise moment in the video where the name of the city is inserted. That's 749,000 minutes or 12483.33333333333 hours. There are 8760 hours in a year so if you were doing that - and only that - no sleep, no other task - it would take you 1.42503805175038 years to complete that task. In a week there are 168 hours.
Minus 56 hours (8 hours of sleep / night)
Minus 45 hours (42 hour work week)
That puts you at 70 hours / week to work on this project.

70 x 60 = 420 minutes a week. 749,000 minutes divided by 420 minutes a week = 1783.333333333333 weeks to do that project. 1783.333333333333 weeks divided by 52 weeks in a year = 34.29487179487179 years to do this project!!! 34 years from today - 9/20/2017 - is Wednesday, September 20, 2051. I would be 81 years, 9 months, 2 weeks, 2 days, which is 29875 days from now.
