Draco: We shall shake on it. An unbreakable vow.
Voldemort: By the end of tomorrow night, Albus Dumbledore will be dead?
Draco: Yes and I will have my rocket ship?
Voldemort: When the technology is mailable.
Draco: AND YOU HAVE TO BE MY SLAVE FOR A WHOLE DAY STARTING NOW!
Voldemort: YOU LITTLE SHIT! You got me! Oh, that is so embarrassing. Oh, that’s the second time that that’s happened. That’s why I hate unbreakable vows.
Draco: There are so many things I’m going to have you do for me. You’re going to clean my room, and lay out my knickers, and you’re going to tape Wizards of Waverly Place for me!
