Panelists Paula Poundstone, Peter Grosz and Faith Salie will be on hand for today's stage show of National Public Radio's game show, Wait Wait...Don't Tell Me! Host Peter Sagal leads a rotating panel of comedians, humorists and journalists through listener contestants and a comic review of the week's news. Contestants vie for the most coveted prize in all of public radio: a custom-recorded voicemail greeting by scorekeeper emeritus Carl Kasell. The event begins at 7:30 p.m. at the State Theatre. Tickets are $37 to $127. (Niesel)
