Hey, listen up, chucklenut. This "joke" plays on the double meaning of "coming out of the closet." See, when someone's gay, they "come out of the closet" by telling everyone. But orphans don't have parents, and usually parents are in a closet, and this is where the joke comes from. You probably eat crayons, don't you?
