Query: A Schwarzian on the Stretched Horizon   It is well known that the Euclidean black hole action has a boundary term at
the horizon proportional to the area. I show that if the horizon is replaced by
a stretched horizon with appropriate boundary conditions, a new boundary term
appears, described by a Schwarzian action similar to the recently discovered
boundary actions in "nearly anti-de Sitter" gravity.
