When Lucy wants to make Julia laugh, she tells her jokes. Such as, "Did the ladybug sting you?" with the italicized part done in a super high-pitched voice. Or, "Did the blap sit on your drap?"
When I want to make Julia laugh, I say things like, "Are you my little fatty? Are you a little nozzleberry?" and blow raspberries on her belly.
When Julia wants to make us laugh, she smiles.
