Dame Edna stoops to conquer NPR's Wait Wait ... Don't Tell Me!

From the transcript:

SAGAL: Later on, we're going to be joined by our special guest Dame Edna Everage, international susperstar. Now if you don't know her, Dame Edna is the creation of the great Australian comedian Barry Humphries. Now we've never interviewed anybody quite like her, so all of us are going to be performing as characters ourselves to make Dame Edna more comfortable. For example, Bill Kurtis right here will be appearing as the adorable Lady Annabel Fotheringay.
