I have to ask, why is it scrawny twerps are what now pes for a "hot Hollywood leading man"?

You know who I'm talking about, the drug addict from Twilight, Justin Bieber, and any one of those acne cases from various CW network shows that's in desperate need of a haircut. Even as old as he is, I would still pick Clint Eastwood over any of them. Explain it to me someone, because I don't understand what is so great about these unmanly dorks.
