The cops tailed one of my bros pals, put on the lights and told him he was weaving - he just replied he was trying to avoid all the bloody potholes (not my tack in that situation - I'd be all yes sir, no sir) so they started telling him that he was speeding, but he knew for a fact that he wasn't so just kept telling them he was doing 30. They eventually realised he wasn't drunk, and knew he wasn't speeding so left it at that!
