Mr. Yuk is mean, Mr. Yuk is green. Mr. Yuk means no! Protect families, especially small children, by using Mr. Yuk stickers. In addition to being a good warning signal, Mr. Yuk stickers also have the emergency telephone number for the Wisconsin Poison Center printed on them. Poison Center nurses are ready to respond to accidental poisoning 24 hours a day, 7 days a week. (50 sheets of 10 stickers per pack.)
