Bob Hope used to poke fun at his humor by explaining it. The idea was that if you have to explain the humor (because the audience didn't laugh at a joke), the joke is dead. Kaput. But somehow he made this self-depricating exercise funny. Humor laughing at itself.
This literary device is very obvious to me. I'm jealous I didn't think of it first. Copying his style would be insincere.
Humor is quite an effective weapon. I used to give incredibly long written tests to the UVa Uechi students. I made them so nobody could get a perfect score. I maintained that record through several thousand students. Then I moved to Richmond and Rich got the first 100% score. Anyhow...through the ridiculousless of the test, I would have one really, really absurd question. It would be something like "What distracts you most during sanchin?" or "What do you want for Christmas?" Extra points were given for entertaining answers. Yes, humor is an effective weapon.
More than one skinny kid saved his rear growing up in a tough neighborhood by being incredibly funny. Make Bruno laugh and he won't steal your lunch money.
An excellent example of this "technique" was displayed at a camp a few years back. As I recall, sensei Malone was teaching one of his "healing touch" seminars ;-) This one skinny black kid from Canada turned out to be one of the "squealers" in the crowd - he grimaced and made noises when you hit his pressure points. Sensei Malone loves to demonstrate his technique with someone who is dramatic like this. Later on that night, this gentleman - who was a professional comedian - gave a show. Sensei Malone was there in the front row, along with his beautiful wife. So were many of his buddies. He did a ventriloquism routine with a black dummy. Let's just say that this wooden dummy said things that this fellow never ever could have said and gotten out of the room alive. And everybody laughed - including sensei Malone.
Other examples of this type of device include "Mr. Hat" in Southpark, or "the evil twin" when describing one's behavior.
I will not torture prima facie humor. I'm no Bob Hope.
P.S. On the other hand, I can't vouch for their sanity.
