'Yesterday, upon the stair, I met a man who wasn't there! He wasn't there again today, Oh how I wish he'd go away!"
The Antigonish T-Shirt celebrates the chilling poem by American educator and poet William Hughes Mearns.
Written in 1899, Mearns' poem was inspired by reports of a ghost of a man roaming the stairs of a haunted house, in Antigonish, Nova Scotia, Canada.
Over the years the poem has taken on a life of its own appearing, in one form or another, in scores of films, TV shows, songs, novels and stage performances.
