How do you write quotation marks

1) 'foo'
2) "foo"
3) ``foo'' (faggot)
4) other

I actually invented this meme (ie. the asking of a ``How'' question in the thread title, followed by four options, with the third invariably being the ``faggot'' option.)

Other memes I invented include the popular ``forced indentation'' meme, which I invented one day when I was trolling the ``Bad things about Python'' thread. I also invented the meme of using `` quotation style.
