My Personal Venn Diagram Exploded: or, There Goes Another Stritchy Clone

On her new album Laurie Anderson just swiped a joke from Stritchy. (you can stream the album at NPR right here)
It reminds me of the time I saw Stritchy at the Cafe Carlyle, and in the middle of "Send in the Clowns" she sang "We should put some mountains over there. Otherwise what will the characters fall off of?" Or not.

Isn't it? Isn't it just like a performance artist?
