Let me start by saying I DO NOT CONDONE DRUNK DRIVING. If you have had too much to drunk, sleep where you are, or call a cab..
This looks like a spoof, but it's pretty funny...
YouTube - How to pass a drunk driving test
After watching the video.. I have talked to a good friend of my who is a local police officer, he told me the reason they ask people to recite the alphabet back wards is because the person usually says "I couldn't do that if I was sober." OPPS!
Remember all TBR people, it's a lot cheaper to call a cab and get your car tomorrow then it is to drink and drive!
