Yesterday, I opened up my old "Racine" brand razor and cleaned out the whiskers that were in it. Afterwards, I turned it on and I noticed it was quieter. But a minute later I noticed that the familiar "buzz" came back, so I applied some machine oil on the blades. Then I turned it on and my bathroom GFCI tripped. 

1...Did that old 1960's razor finally receive a ground fault? 

2...Had it not been plugged into a GFCI outlet, would I have been electrocuted instead? 

3...Did my opening it up to clean it out have anything to do with it?

I did not spill any water on it. And
I don't think my applying oil on the blades had anything to do with it, as I have done that many times before. But this was the first time I have ever opened it up to clean it out. I also noticed something was rattling loose inside it shortly before the GFCI was tripped.

In any case, it looks like it's time for me to buy a new razor! And when I throw out the old razor, I'll be sure to cut the cord off first, lest some dumpster diver (like me) pick it out of the dumpster.
