This is a short spoken line asking what someone is wiping the windows for, delivered as a flat, puzzled question in about a second and a half. The deadpan curiosity makes it funny because the task sounds pointless, and the brief delivery leaves the confusion hanging. It works as a quick reaction to unnecessary cleaning, busywork, or someone fussing over something already clean.
