A lot of convention speakers insert claptrap in their talks, maybe to massage their own egos. It also pads out an way-under-time talk!
Do they have it in their notes?
Perhaps like this:
"Brothers and sisters, aren't you glad to be here?"
(Pause for long applause)
"The faithful and discreet slave have certainly given us food at the proper time haven't they brothers?"
(pause for long applause)
