Also, that GIF up there. "Someone grab him!" SERIOUSLY.
2. Least Favorite Muggle
Let's be honest... there really aren't too many choices here. There are maybe 6 or 7 Muggle characters of any importance in the HP series, and you can't pick someone like the Muggle Prime Minister (loved that chapter) or Frank Bryce. I have to go with Aunt Marge.
A really despicable human being. "I'll be welcomed back like a hero!" Ew.
4. Least Favorite Hogwarts Teacher
I feel like there are plenty of teachers to pick from here, which is unfortunate. However, I think my final answer is going to be Professor Binns.
