Stessel's Button (DVD and Gimmick) by John Stessel - DVD
You are the victim of a strange wardrobe malfunction. One of your shirt buttons has been mistakenly sewn right nest to another button. This tragedy would leave the average person in a sad, hopeless sludge of mis-buttoned humiliation. But you are better than that!
As your empty fingers gently tug the edge of your shirt, the out-cast button slowly begins to animate.. gradually inching its way up your shirt.. Astonishingly sliding up to its proper position.. where it stops!
Someone immediately tugs on the haunted button and examines everything. The button is genuinely sewn to your shirt!
