Heavenly Daze(1948)

Shemp dies but cannot get into heaven until he reforms Moe and Larry. He returns to earth as an invisible spirit and sets out to prevent the other two stooges from selling a phony invention (a fountain pen that writes under whip cream) to a rich couple. Shemp sabotages Moe and Larry's sales pitch, but it looks he's headed for the fires below anyway.
