Hulk Thumps Nick With "Heavy Stuff"

When Nick Hogan talks to his dad from jail, he's a completely different person than when he's with his mom. He sounds like a seminary student, not a blithering mess.

On the other hand, WTF is Hulk talking about in this clip? "Listen to the silence?" "Acknowledge it as being in the now?" "I will bible thump you?"
