Henry Work's Grandfather Clock

Introduction
Henry Clay Work, the writer of "Marching Through Georgia", also wrote the song, "My Grandfather's Clock". This clock is said to be the original inspiration for his song, since it belonged to his Grandfather.

Effects
If someone hums "My Grandfather's Clock", they will have visions of nostalgia, and relive their best memories. The memories in particular involve that person's relatives, and the only way to stop it is if they stop humming the song. If the clock ever stops, then anyone who stands in front of it will die, so it constantly needs to be rewound.
