This is a classic kids party game. It's simple and a lot of fun for younger children.
Kids sit in a line and the first one makes up a sentence. They then pass the sentence along by whisppering in each others ears(it has to be so quiet that noone else hears it). The last kid in line than announces what got to him.
This game is better for younger children, since to whole point is that something totally different and funny comes out at the end of the line.
