How to get my friend to watch the sopranos?

So I have been telling my friend about this series and how great it is for about 3 years like every other month. He always tells me he will watch it SOON, but he never fucking does. I swear if he was any body else, he would have gotten his intervention right in the back of his head.He has become weak, hes out of control and hes become an embarresment to himself and everybody else. But fr, what do I do without spoiling him?
