“Here, hold muh — never mind!”
Some DUI lawyers recommend that their regular clients keep a bottle under the front seat. If they have an accident, they're to bring it out and consume heavily in front of all the witnesses until the cops arrive. If they're not paying attention, offer them a swig.
Later, in court: "Ladies and gentlemen of the jury, the evidence clearly shows that my poor client, who wouldn't think of driving under the influence, was a model of sobriety while he was operating that motor vehicle.
He was so upset about that unfortunate accident, though, that he had a few drinks while they were all standing around waiting for the officers to show up...
It works, as often as not ("reasonable doubt"...).
