Put it at the end of a fail sequence, after the mistake has already happened, then follow it with Goofy Ahh Sounds for a second reaction beat, or with Emotional Damage when the failure stings. Keep it as the closing reaction, not the opening gag.

This clip is Mario's gibberish from SMG4 stretched to an ultra-slow crawl for about four seconds, his familiar nonsense syllables drawn out into a warped, wobbling ramble. It feels absurd and disorienting, funny because the cheerful chatter turns sluggish and strange. It comes from SMG4's Mario Gibberish 1, slowed down.
