" AAaargwannawannaaaagongongonaargggaaaaBLOON!" which is the traditional sound of a very small child learning that with balloons, as with life itself, it is important to know when not to let go of the string. The whole point of balloons is to teach small children this. "

― Terry Pratchett , A Hat Full of Sky (Discworld, #32; Tiffany Aching, #2)
