I have a nine-year-old son who thinks it is hilarious to take me in by knocking on the door when I am in another part of the house, then laughing when I go to see who it is, and other jokes of the "made you look" variety. The response I have settled on for this type of "humor" is to smile slightly to acknowledge that it is a joke, segue to a mildly disgusted look to show how little I appreciated it, and then press on.
