Place it at the exact cut between the old scene and the new one, then let the next shot establish the changed situation. For a stronger payoff, follow it with SpongeBob Sad Song when the wait ended badly, or with You What when the new scene needs a confused reaction.

This is a short 1.6-second spoken time card in which a narrator announces 'Many months later.' It feels dry, patient and quietly funny, turning an ordinary wait into a joke about how much time has passed. It comes from SpongeBob SquarePants, where time cards bridge scenes with a single dated caption.
