Making Jokes

So, my usual m.o. in class is to teach for a couple of seconds then make a bad joke, laugh at it myself, point out to the class how funny I am, and then berate them for not appreciating me enough.  Something along the lines of:

"When Newton wrote Principia, no one was forcing him to accelerate mankind's understanding of science." (slight pause) "Get it?  See what I did there?  Forcing?  Accelerate?  I'm funny." (serious students looking perturbed at their learning being interrupted, non serious students annoyed that I might actually think that was funny, and politically savvy students fake laughing).  "Oh - tough audience today."  (Sigh)

So, imagine my surprise when today I inadvertently made a funny while talking about circular motion (the need for a tangential velocity coupled with a centripetal force).  After some off topic remarks by some of the clowns* in the class, I try to bring us back to the physics with a "Usually, I like it when we go off on a tangent, but this is a bit much..."  Then I pause in confusion as they are all groaning and laughing at me.  Then I realize what I had done and promptly said "I gotta blog this."

Am I training them or are they training me?

*This is the same class where one day when they were leaving, I said "Usually, I'm the weirdest person in a room, but in the class, I'm not even in the top five!"
