pin the tail on the donkey

This is an electronic version of an age-old children`s party game. The game is extremely simple. A large picture of a donkey (less tail) is pinned up on the wall. The contestant is blindfolded and provided with a `tail` which must be pinned in the appropriate location on the donkey`s posterior. The area around the tail location on the donkey is marked off with concentric circles denoting scores; SO for `bull`s-eye` ( or should we say `donkey`s ... `?!), 25 for first circle and so on.
