The popular NPR news quiz show Wait Wait...Don't Tell Me recorded this week's episode at the Mahalia Jackson Theater last night in front of a packed house. The episode will air at 10 a.m. Saturday on WWNO 89.9 FM. Host Peter Sagal and judge/scorekeeper Carl Kasell (pictured) were joined by panelists Mo Rocca, Roy Blount Jr. (author of Feet on the Street: Rambles Around New Orleans) and Amy Dickinson. George Porter Jr. was the celebrity guest tested on an area of knowledge totally unrelated to his expertise. He also was quizzed about the meaning of Mardi Gras Indian and Meter song titles (but it seemed no one briefed Sagal on how amicable the Meters breakup was). Tune in to hear the secret of a professional musician staying married for 43 years; what Dickinson thinks Houston is for; thoughts on the tickling and nudist habits of congressional members; and Mo Rocca's bold prediction about Drew Brees' greatest secret.
