Another hat tip to SC for this one...
A frustrated motorist paid a parking ticket with a check which expressed his sense of unfairness on the memo line. "Bulls***t money grab" he noted for his financial records. He send in the check. And then...the cops showed up. He was being held in contempt of court.
Alas, though the ACLU was ready to rush into the breech, the ensuing free speech showdown never happened. Another check--this one without the offending words was tendered to the court.
