"Did you hear?" Andy asked. Donna asked, "Did I hear what?" Andy said, "Ground beef contains pink slime. I don't know what pink slime is, but it sounds bad." Donna said, "I'll tell you what pink slime is. It's trimmings from the cows. They used to put it into dog food. Then some guy figured out how to process it. He added ammonia to kill the bacteria. That way the slime was fit for humans. He sold it to beef processors. They added it to ground beef. The slime made the beef cheaper. Pink slime has been around for years. It won't make you sick. It just sounds yucky." Andy said, "I bet it looks yucky too. Well, no more ground beef for me. I don't care if it is fit for humans. I wonder what else I've been eating all these years." Donna said, "You don't want to know."
