A friend told me about someone who had gotten off scotch free.
When asked, she gave a glowing explanation on how scotch was correct, because the penalty didn't stick. (Yes, she was blonde)
scot free The expression scot free derives from a medieval municipal tax levied in proportional shares on inhabitants, often for poor relief. This tax was called a scot, as an abbreviation of the full term scot and lot, where scot was the sum to be paid and lot was one’s allotted share. So somebody who avoided paying his share of the town’s expenses for some reason got off scot free.
