Sometimes I think Durnell’s style is just to set up everyone to be either happy or cranky, and then steer them another way.  At least, if you do this half the time or more, you keep people on their toes.  I suppose that’s part of an Emcee’s job- keep folks guessing and listening close.  Keep ’em holding their breath and waiting on the other shoe to drop so they can’t interrupt.  Baffle them with Bull… You get the idea.
