Place it at the end of a short fail or family clip, just after the reveal, as the closing reaction. For a bigger laugh chain, follow it with Nelson's Ha-Ha! and then the Laughing Dog Meme, letting each laugh answer the one before it.

This short clip is simply an older man laughing, a hearty, slightly wheezy chuckle that lasts just under three seconds. It feels warm, goofy and instantly disarming, like catching a grandpa mid-joke at the dinner table. The laugh is broad and unguarded, turning an awkward pause into something friendly and easy to join in with.
