Once I said to an orphan, "What the 'F' means in 'orphan'?"
He replied, "There's no 'F'."
Me: "There's no family."
Listen up, genius. The joke plays on the word "orphan." The dude asks the orphan what the "F" in "orphan" stands for. The orphan says there is no "F." Then, BAM! The joker says that the "F" stands for "family," which orphans don't have. It's funny because it's sad, and you are a sad excuse of a human.
