I suggest that taking a piss on anything in Arlington would be a very bad idea. Moreover, I really suggest you not piss on the beret, if there is still one there. Considering what came later, JFK was was a lesser evil. However, if the bury Clinton in Arlington, I'll have to rethink the above.
I agree with you about the urination thing. The only grave I want to p!ss on is that of The Former Impeached President BJ (Blow Job) Clinton. I'm drinkin' beer and holding my water for that one. And he will NEVER be buried in Arlington, not as long as there is one military vet left in these here United States.
