Unsurprisingly security is pretty hot on at the White House , I remember walking around the grounds with a couple of mates making wise cracks about Monica Lewinski and bobbing heads seen through the window , we then spotted an open door and I suggested we go and have a look around , within 20 seconds three plain clothes guys came running from nowhere and made it quite clear the trying to enter the White House was a bad idea, I`m pretty sure they had been listening to all of our disrespectful conversation by some listening device.
