My favorite way to lecture is to pass out a personally written chapter on the subject and then collectively read the hand-out. I call this lecturing "Seder-style" named after the ritualistic dinner of the Jewish holiday Passover.

I used to have a print service that did this for me but it stopped working when I upgraded to Snow Leopard. I found this web service BookletCreator which does a great job with this.
