I have seen that phrase somewhere on the Internet, I couldn’t remember how it was punctuated. I want to give it a try and see if either punctuation marks or the connection word would work.
I don't understand the question at all. None of the words you've quoted go together at all, let alone as a phrase you would see (on the internet or otherwise).
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
