What is it called when a character is portrayed opposite the stereotype for comedic effect?

Many character roles have stereotypically defined behavior, e.g. macho soldiers or helpless princesses. Sometimes authors intentionally defy those stereotypes for humor, and to call attention to readers' usual assumptions.

What is the name of this literary device, where an author flouts a stereotype for humor?

I can't think of an appropriate word (or even short phrase) for the life of me. Any thoughts appreciated.

For example, a comic depicts Shaolin monks, but instead of following their stereotype of being silent and serious, there is corny humor and a spit-take.

Solution 1:

tvtropes.org might not be the guardians of the English language, but they certainly have plenty of know-how regarding to tropes (such as stereotypes) and have defined or documented much terminology in this area.

They call this inverting a trope, or more precisely a stereotype flip. Stereotypes can be considered a sub-set of tropes (or the other way around).

Solution 2:

There is the word counterstereotype.

The Wikipedia has this page for the word, where it is defined as:

A counter-stereotype, reverse stereotype, or anti-stereotype is the reverse of a stereotype. Although counter-stereotypes arise in opposition to stereotypes, they may eventually become stereotypes themselves if they are too popular.

EDIT: note that counterstereotypes are not necessarily used for humor. They can be used, for example, as a protest against the stereotypes. The Wikipedia page that is linked above has some interesting examples.
