Creepshow Travelling Ashtray

While watching "Creepshow" the other night, my wife noticed what has been referred to as the 'travelling ashtray'. Apparently, this ashtray belonged to George Romero, and for whatever reason, he decided to have it appear in every segment of "Creepshow". The following shows where the ashtray appeared in each story.
