I want some of what she's on! Kristin Chenoweth stopped by tonight's “Late Show” to, in theory, plug her upcoming ABC dramedy, “GCB,” and catch up with David Letterman. Instead, we were treated to a rambling tale of eyelash extensions, formaldehyde allergies, Asian stereotypes, anti-inflammatory medication, Vicks VapoRub (in the nose, to kill bacteria), neck braces, falling earrings, and dear lord will someone please come carry her off the stage?
