The location in which the Best Of show introduction and inter-segment bits were recorded was not mentioned at the beginning of the show.
For the Bluff the Listener segment, each panelist paired up with a Wait Wait Junior to write and present their bluff story. The bluff story that Mo Rocca worked with his Wait Wait Junior included a person named "Polly Poundsteen" in reference to Paula Poundstone. The two Wait Wait Juniors that paired up with Maz Jobrani were actually his own kids.
To determine who would get the point for the Bluff the Listener segment, the audience was polled to see which one they thought was the correct one by way of applause level.
