Another strong candidate is an analog horror series on YouTube called In Episode 4 ("Bedside"), a son named Bill is told to wake up by a figure he assumes is his mother. The mainstream episode ends with static. The Patreon-exclusive extended cut includes the whispered confession, leading fans to call it the "I’m not mom exclusive ending."

There is no clear context for why she is screaming or why she keeps saying "exclusive," which allows users to apply the sound to almost any confusing scenario.

The phrase "Bill, wake up! I'm not Mom" may not be exclusive to "Sabrina the Teenage Witch," but its place in the hearts of fans is secure. As pop culture continues to evolve, one thing is certain – this phrase will remain an unforgettable part of our shared comedy heritage.
