South Park: How to Eat With Your Butt

Once Cartman believes he has seen the funniest thing ever, he regretfully realizes he may never see anything as funny again. As part of an elaborate joke, Cartman manages to get Kenny's school picture plastered all over every "missing child" milk carton in the country. Cartman finds everything about his prank funny until a very strange couple turns up in South Park searching for their lost boy.
