"We've been asking consumers for their questions about McDonald's food," explains the McDonald's tour guide at the start of the video. "And the No. 1 category, by far [is] Chicken McNuggets, specifically what's in the Chicken McNuggets." McDonald's goes on to explain that its chicken nuggets contain no "pink slime," which is a nickname for the meat-based goo that has been banned for human consumption by the European Union. McDonald's also wants to make sure you know that there are no beaks or feet in its nuggets and that the meat only comes from the chicken breasts, thighs and other parts of the chicken that people normally eat.
