At nearly 17 seconds, this voice recording is longer than a quick stinger, so it usually works without trimming when you want the full prank timing. Download the MP3 to keep it available offline, then assign the file as a ringtone or notification tone through your phone’s sound settings. Its spoken delivery can compete with dialogue, so lower background audio or wait for a quiet gap. Keep a shocked reaction sound ready for a follow-up, but avoid layering both clips at once.
