Kourtney and Khloe ensured that we'd never take mayonnaise on our club sandwich again after an appearance on "Chelsea Lately" during which the sisters copped to using the condiment as a feminine hygiene product. "She puts it on her Pikachu," Khloe explained, also ensuring that we'd never look at our nephew's Pokemon collection the same way again. "See, Kourtney has -- because we're Armenian -- really course, thick hair -- especially down there. So the mayonnaise moisturizes it and makes it softer. Kourtney does it all the time. She likes me to apply it." "Nightly," chimed in Kourtney. "Because I get all the cracks. … Cause that's what we all want is a shiny vajine. I want it to sparkle," concluded Khloe. Well, we guess that's one way to return the favor of the at-home wax session. We just hope none of you had tuna salad for lunch!
