In my jurisdiction, one of the criteria for de minimis is this:
The court may dismiss a prosecution if, upon notice to or motion of the prosecutor and opportunity to be heard, having regard to the nature of the conduct alleged and the nature of the attendant circumstances, it finds the defendant's conduct:
...
C. Presents such other extenuations that it cannot reasonably be regarded as envisaged by the Legislature in defining the crime.

Is that a typical way to get your offense to be considered "de minimis"? That seems like a rather glaring hole.
Please include in your answer what is typical of "de minimis", whether or not my jurisdiction's criteria is typical, and at least one odd example of where the concept of "de minimis" has been applied especially if it is with regard to my jurisdiction's criterion.
