Sheri and Dr. Kate hang out in Phyllis Diller's costume room. Check out the zebra covering on the wall and ceiling. You can't see it here, but one entire wall is all wigs from the rainbow afro wig to the spiky wild woman wig. You can see a few of her costumes off to the side. The room was filled with fun sequin costumes with feather boas and all kinds of other good stuff!
Here is a portrait near Phyllis Diller's fireplace. If you look very closely you'll see it's a collage of everything from bottle caps, to a can of Beef Bouillon to hair spray cans to a tube of Poli-Grip to plastic hair rollers. Such fun.
While I was there I bought a piece of art called "Four O'Clock Kitty Time" and also asked Ms. Diller to sign a photo.
