The laughing matter is a fourth wall breaker; It's funny because Pearl is a bird. You don't have to get it because Lapis and Peridot's shared sense of humor could be a bit of confusing. (Like in the 'Responsible Earth Citizen' zine comic, and in 'Gem Harvest'.) --------- A sirin has a head and the chest of a woman and the body of a bird, and is attributed to sound/music.
