Q: You know those 2 little metal things that you plug into the outlet? Well, I was sizzling, and so I took it out, and it was little bit burnt. Only the tip, is it still ok to use?
A: NO! Sizzling is not good. My guess is that it's a problem with the particular outlet you were using not the Mac connector. But get it checked out by someone who understands electricity before you try again.
