A few years ago when Julie Kavner was on Letterman he asked her to do Marge and she said she didn’t really want to because she didn’t want to shatter the illusion for the fans of having such a famous character’s voice come out of her face.
To which, in classic Letterman style, Dave replied, “Ah that’s a load of crap - Do the voice”.
This got a huge laugh so Kavner turned away from the camera and did a few lines. She didn’t seem annoyed.
I agree Lipton is the most humorless person on Earth, but I didn’t think the ‘improv’ Q&A was all that bad. Some were so good I thought they might have been scripted ahead of time (Yeardly Smith’s poem bit obviously was). I thought Dan C. and Harry Shearer were pretty quick on their feet. I loved Shearer telling the audience member to find his seat when he did Principal Skinner. And when asked what his favorite swear word was having Krusty say, “Aw f*** it!”
My biggest disappointment, besides the show not being 2 hours or at least 90 minutes, was Lipton not having a question for Groundskeeper Willie. I can only imagine how Willie would react to one of his inane inquiries!
