Check out this photo courtesy of Cop Humor: the Lighter Side of Law Enforcement! Here is a perfect example of self-deprecating humor . . . this type of humor has been defined as “a powerful form of humor that gets its strength from highlighting your own (real or imaginary) weaknesses or idiosyncrasies.” (Definition is courtesy of http://www.speaklikeapro.co.uk/Self_deprecating_humor.htm.)
This can work for an individual in any speaking situation and I would posit that it works equally well for defusing group stereotypes or similar behaviors (as evidenced by this photograph — we all know the cops and donuts stereotype, don’t we?).
Regardless, humor is humor and some is truly hilarious! Enjoy!
