Treehorn says “The brain is the biggest erogenous zone. The Dude says “On you maybe”. 😂 Is he bragging about his Johnson size?

I think it’s because he initially believes that Treehorn is behind the whole caper. You do have to remember that it was Jackie’s goons that micturated on his rug in the first place. Completely unprovoked. And that rug really tied the room together, did it not? I would have immediate hostility against Woo and his buddy’s boss, too, if I knew that Jackie employed the carpet pissers.
