Sam Forstman is an old man who lives with his granddaughter Marnie Kirk and her husband Doug. Sam lives a simple life and doesn't sleep much anymore. He's usually up at all hours tinkering on his grandfather clock, something that worries Marnie as his attention to the timepiece verges on the obsessive. The reason for that however is quite simple: he is convinced that should the clock ever stop, he will die. Written by garykmcd

Narrator: [Opening Narration] Each man measures his time; some with hope, some with joy, some with fear.

Couldn't help feeling for the silly old fool.
2 December 2013 | by darrenpearce111See all my reviews

A whimsical story about a gentle, eccentric old man with a peculiar obsession with a grandfather clock. Best taken as an allegory not to let superstition or the past stand in the way of the present. Any supernatural element here might be taken as though merely psychological. Besides that Ed Wynn is larger-than-life enough, in a gentle way, to make the viewer see past the silliness of the tie-in with the Victorian clock song of the title. The story would be better without making that direct association.

Thanks to Ed Wynn (Mad Hatter's voice in Disney's 'Alice In Wonderland', as well as having acted Serling's own writing in 'Requiem For A Heavyweight', and in TZ 'One For The Angels') this becomes engaging on a human level.
