A salesman rings the door bell and Little Johnny answers. Salesman: "Can I see your dad?" Johnny: "No, he's in the shower." Salesman: "What about your mother? Can I see her?" Johnny: "Nope. She's in the shower, too." Salesman: "Do you think they'll be out soon?" Johnny: "Doubt it. When my dad asked me for the Vaseline, I gave him super glue instead."
