Cursed Beer Glass

A young man is drinking some beers with his grandpa until his beer runs empty. He walks to the fridge to grab another beer and begins pouring into a glass, only, as he pours the beer into the glass, the glass does not fill even as the beer bottle empties. He calls a friend about it, who speculates that the glass has apparently been cursed by a witch, to which his grandpa later confirms it to be true.
