Place this clip at the start of a scene, right before the person being called appears on screen. Follow it with a door sound and then a surprised reaction sound, so the edit moves from the callout to the entrance and ends on the group's response.
Über diesen Sound
This is a 29-second voice clip built around a single drawn-out call of 'Tante...' said as if calling an auntie over. The stretched delivery makes it feel awkward and amused, like someone holding a call out on purpose while waiting for a reaction, and the longer it hangs the funnier the waiting becomes.
