Why can't orphans go to family restaurants?
Because they don't have a family to go with.
Alright listen up, buttercup. The joke is about orphans, which are kids without parents. Family restaurants are restaurants for families. Orphans don't have families, so they can't go to family restaurants, duh. It's so obvious that it went over your head because you are so dumb and naive, LOL.
