Ice cream vans are often brightly decorated and carry images of ice cream, or some other adornment, such as cartoon characters. They may have painted-on notices, which can serve a commercial purpose ("Stop me and buy one!") or a more serious one ("Don't Skid on a Kid!") - serving as a warning to passing motorists that children may run out into the road at the sight of the van, or appear without warning from behind it. Along the sides, a large sliding window acts as a serving hatch, and this is often covered with small pictures of the available products, with their associated prices. A distinctive feature of ice cream vans is their melodic chimes, and often these take the form of a famous and recognizable tune, usually in the United States "The Mister Softee Jingle", "Turkey in the Straw", "Do Your Ears Hang Low?, "Pop Goes The Weasel", "The Entertainer", "Music Box Dancer", "Home on the Range", "It's a Small World", a tune from the opera Le devin du village more commonly known as the American folk song "Go Tell Aunt Rhody", "The Picnic" (a Japanese children's song usually played with a recording of a young woman saying 'hello' at the beginning of the song on ice cream trucks), or "Camptown Races"; or, in Australia, New Zealand and the United Kingdom, "Greensleeves", "It's Now Or Never (song)", "Whistle While You Work" in Crewe and Nantwich, "You Are My Sunshine" in Vale Royal, "Teddy Bears' Picnic" in Sheffield, and "Match of the Day" in other places. In some places in the US, ice cream trucks play the song "Ice Cream" by Andre Nickatina (essentially just Turkey in the Straw with bass).
