I also got to see them in "Good Evening"--I believe it was in Philadelphia. I'll never forget the "Frog & Peach Restaurant" bit.

"Why did you name your restaurant 'The Frog and Peach'?"
"It just occurred to me that there was really no restaurant in town where one could get, both, a really good frog, and a really good peach."
"I see. And can you tell me about your menu?"
"Well, we actually have just two dishes. One, Frog a la Peche, is a very large frog, baked, with a peach in its mouth. And the other, Peche a la Frog, is a really huge peach, stuffed with dozens of tiny frogs."

Aloha,
