Replying to My brother has a Vagina

So I was watching Entourage, minding my own business, being a man and such, and my brother grabs the remote and changes the channel to pirates of the caribbean, like the 2nd or 3rd one, nothing special. I grab it back and lecture him how he has a vagina, choosing said movie over the best show ever. I tell him to give it a chance and he walks up to the tv, changes the channel, then turns off the tv. He's now in his room pissed off. He's 16.
