An officer was watching a drunk; as he staggered to several cars before finding his own and passed out inside. After a while when he awoke being the last to leave he pulled out and was immediately pulled over, given a sobriety test he passed being totally sober, the officer couldn't explain it, thought perhaps it was his equipment, then the "drunk" explained that he was the "dd" for the night, Designated Driver the officer asked, no designated decoy came the reply.
Hope you had a safe and happy new year
