Doctor: I've got good news and bad news.
Patient: What's the good news?
Doctor: I've got you flowers.
Patient: Awww, What's the bad news?
Doctor: They're for your grave.
The doctor initially presents the news in a way that suggests something positive is coming. He gives the good news which is 'I've got you flowers'. The patient responds positively, but the punchline reveals a dark twist, the flowers are for their grave, which they will need since they are going to die.
