This 17-second music clip is compact enough to use whole, though you can trim it around a shorter reaction. Keep it below dialogue because the melody can compete with quiet speech. Download the MP3 for offline playback, then assign the file as a ringtone or notification tone if your device supports custom audio. For layered jokes, follow it with SpongeBob Boowomp or JoJo To Be Continued. Avoid stacking loud effects over the most emotional section.
