3 boys were having a debate about who had the healthiest grandma.
Boy 1: "I have the healthiest grandma. She is 67 years old and can still do a backflip!"
Boy 2: "No, I have the healthiest grandma. She is 76 years old and can still finish a marathon!"
Boy 3: "I have the healthiest grandma. She is 85 and she is in the hospital..."
Boy 1 and 2, looking confused.
Boy 1: "If she's so healthy, why is she in the hospital?"
Boy 3: "Because she's giving birth right now!"
