Hang on so he is collecting piss to use at a later day? i.e. when the planet runs out of water? or does he pour it on the gimps on his bus tour?
Also the fact that your family said that to you is a fucking joke.
What you should do is take the bottle of piss and make a trail of them all the way to their house so when your brother picks up the final one you can shut the front door on him in that house lol
