There were people at the conference that were showing off neat stuff and smiling a lot and shaking hands and acting like they wanted to help.  Bongo liked this one because they had moving pictures and sound.

Bongo was hoping he could get one of the Schlum-burgers to eat, because he was hungry, but it turned out you can’t eat a Schlum-burger.

But they were nice people and let Bongo watch the moving pictures over and over again. The people said that they had seen it all they wanted to, so they didn't watch.
