While I don't have the exact quote, it's something more along the lines of "my actions caused the creation of the Internet" or "the Internet wouldn't be here if it weren't for me." There's actually not one quote since it was multiple instances that he took credit for the Internet (as we know it today). And not wrongly, really: he sponsored bills which provided federal funding for the Internet backbone system and the broadband consumer transport networks that define the Internet we use today.

But of course it was all too easy for some people to claim that he was taking credit for TCP/IP and HTTP.
