Sesame Street "Crack Master" Short from Episode 818 (1975)

On Thursday 10th February, 1977, during the first 15 minutes of Sesame Street Episode #979, aired, for the first time, a 1:29 short involving a girl seeing patterns in the cracks on her walls, from a camel, a monkey, a hen, and, most significantly, the eerie Crack Master that appears. The short is narrated (and partially sung) by a woman. It was created by animator Cosmo Anzilotti.

This short was said to be very frightening, as many people recount seeing it as children, and have posted their terrifying experiences on numerous forums. The short only aired a few times in the mid-to-late 70s, and has allegedly never aired since (although there have been multiple claims made that it did air in the late 90s/early 00s during the Spanish adaptation of Sesame Street called Plaza Sesamo, which was broadcast in Latin America).

A man named Jon Armond, in 2009, was able to acquire a copy of the short (apparently from CTW -Children's Television Workshop- Archives, though other sources say that someone close to Anzilotti contacted Armond directly, later providing him with a copy after reading of Armond's search effort online), although he has been contractually forbidden from sharing it in any form, bar private screenings (of which he has held several).

While Armond cannot release the clip at this time, he is currently in the process of making a documentary on the subject, in which the highly sought-after video will finally be shown again, more than 30 years after it was last aired.
