I think A-Rod needed this!!!
Seriously, why else would someone by synthetic urine? You buy this either to:
A. Pass a drug test that you know you are going to fail.
B. Use it to make up some kind of voodoo/witches spell.
C. Play a practical joke on a good buddy (it has to be a good friend. If you didn't like the person, you would just use real urine)
I can't think of any other reason one would buy Synthetic Urine, can you?
