Fran: It's Monday morning, which means Miss Babcock has just arrived. She's handing Niles her coat. She's saying, "Careful, I just cleaned my fur," to which he responds, "Don't cough up any hair balls." And right about now, she's getting even with him.
Niles: (off-camera) Aaaah!
(Niles walks in the room, limping)
Niles: Miss Babcock is here!
