Urine testing by the border

I am just arriving at the US border, and the stupid border control stops me for some questions. I am not very happy with this, but I know I will not be granted access without my cooperation. So I have to show my passport, and he demand that I leave a urine sample for a testing!

He gives me a glass to piss inside, and I cannot believe it! He start swollowing the piss! But it was not enough, and he tell me to piss more in the glass. So I fill the glass with a lot of piss. The border patrol seem to really enjoy swollowing my piss! What is this? After he has consumed all of my urine he tells me that I am under no influence of anything, and are free to enter the country. What a moron!
