The most interesting answer to the question "What happens when you delete your recycle bin?" on Windows operating systems is located on yahoo answers and is sounds like this:

Windows won't allow you to do that because after you delete your recycle bin, it goes into itself and if you empty the recycle bin it goes into a Infinite delete loop that causes your CPU to overload and overheat creating a mini-black hole. This mini-black hole then creates a doorway into the past that part of you computer travels into and arrives just before you deleted the recycle bin and instantly blocks the command to delete your recycle bin and ta-da, nothing happens! It happens so fast and so often, 99.99% of humans don't even know it is happening. Its kinda like dividing by zero. Don't even get me started on where that will take you! The only person who has been able to successfully delete the recycle bin is Chuck Norris. And that was only because his round house went so fast it traveled back in time and killed all the dinosaurs!
