Joke

Harry Potter wakes up with terrible headache. He asks Ginny:
- What was yesterday?
- You were visiting Malfoys, and you came drunk.
After that Harry comes to Draco Malfoy and asks:
- What was yesterday?
- Come tomorrow morning to Shrieking shack and you will know.
Harry is in doubt. If he will go, that could be trap. If he will not go, Malfoy will say that Harry is coward.
Harry decides to go. Coming to Shrieking shack, he sees beaten Ron, tied to shack with ropes.
Harry asks:
- Ron, is that you?
- Yes. Harry, is that you?
- Yes.
Ron starts singing:
- Happy birthday to you!
