Without further ado
Without further ado, lemme explain;
If you want to get going with something then why do you want to add "without further ado", just get on with it. Adding "without further ado" is in fact the ado you added which you could have simply avoided. So, my "without further ado" in the first line of this post is actually not required, but was added to make a point. I could have just started with the explanation and that wouldn't have confused you anyway.
