Girl: I'm having heart surgery today.
Boy: I know.
Girl: I love you!
Boy: I love you more, much more!
...... After surgery, when the girl woke up, only her father is next to her bed.
Girl: Where is he?
Father: You don't know who gave you the heart?
Girl: What? (She starts crying)
Father: I'm just kidding, he went to the toilet.
