Hitler is Informed that the Bunker is Haunted
From Screamer Wiki
Hitler is informed that the Bunker is Haunted is a Hitler Rants/Downfall parody by MaximillianZakes, which uses screamers as its "haunted" theme.
Video
First, Gunsche informs Hitler of the titular event, but at 0:11, when Hitler starts to say, "Why do you keep bothering me with such dumb nonsense, that you know is not true?", he is suddenly interrupted by Reagan from The Exorcist with the exact same scream as The Maze.
The parody humorously continues from there, but at the end, after Hitler kisses Eva Braun, the same screamer pops up again, then says "To be continued..."
