I think David Letterman is a perfect example of an alpha male, and I think all asiring PUA's should tune in 5 nights a week to study and learn from him.
It seems odd, I know... after all, he acts so damned goofy! But upon closer examination you will realize he is a very powerful puppet master, he rules the roust.
Watch how he dominates his guests, sets the frames, qualifies them, etc.
Remember the whole scandal with him screwing his interns? Not only was how he handled that situation alpha, taking the bull by the horns and making no excuses, but more importantly: he's a 60something guy screwing 20something interns!! That gives us all hope. Not looks, not age my friends, but POWER! Power that comes from deep within.
If you study him closely you'll realize that the jokes he says are not actually funny at all, they are quite ridiculous, but it's his attitude, his delivery, his deep inner confidence that allows him to pull it off.
Whenever a HB10 comes on his show, notice how he is shameless about expressing his attraction. And notice how they defer to him in every way... he always charms them!
Anyhow... I can go on but this is getting to be a long entry... alls I'm saying is: we all have a great opportunity to see how it's done... so see for yourself
