Place it just before a reaction shot, then follow with the JoJo To Be Continued sting to freeze the joke, or open with the Giorno Giovanna Theme before cutting to the fake call for a bigger JoJo payoff.
About this sound
The Doppio Turururu clip is Vinegar Doppio's short vocal imitation of a ringing telephone, lasting under two seconds in a steady, looping rhythm. It feels urgent and silly at once, like a private call interrupting an ordinary moment. It comes from JoJo's Bizarre Adventure: Golden Wind, where Doppio hears the boss calling and answers whatever object is nearby as if it were a phone.
