In all seriousness, get some Graphite 'lube' it's just a fine fine powder, try that straight into the nut. If that doesn't work mix a bit of graphite with a bit of vasoline and put it in there. This works great I had to do it to my e, b, and g string due to buzzing a few years ago, I just put the graphite in there straight and it's worked ever since. Oh my old guitar teacher used to tell me if you can't find the lube to just use a No. 2 pencil...it's the same stuff. Hope that helps
