Cop car chasing a speeding car on the freeway; 

Cop turns on siren and flashing lights, drives alongside and the car; speeds up to 160 km

the cop car on it's tail for 10 minutes, speeds up to 180 km, finally the driver pulls over;

the irate cop drags the driver out of the car; " you saw me clearly and you keep on speeding,

just give me one good reason why; been drinking? " only had a couple.

Cop: so ...why drive like an idiot?
