Rumble.com user agatabernard posted a video that made our hearts melt from its cuteness.

The mother in Argentina captured the moment when her twins responded to their big brother's effort to make the babies laugh.

Evidently he's their role model, because the two babies immediately mirrored his silly antics.

The back-and-forth fun is guaranteed to delight everyone watching the clip.
