Are the toys in your child's Happy Meal making him fat? 

The Center for Science in the Public Interest says they are. The Washington-based consumer advocacy group threatened to file a lawsuit against McDonald's Tuesday, charging that the fast food chain "unfairly and deceptively" markets the toys to children.
"McDonald's marketing has the effect of conscripting America's children into an unpaid drone army of word-of-mouth marketers, causing them to nag their parents to bring them to McDonald's," CSPI's Stephen Gardner wrote to the heads of the chain in a letter announcing the lawsuit.
