Minnie's letter to Neville's grandma had to have been hilarious. I liked Trelawney's racial slurs better than anyone else's. Because, wow, that bigoted old witch!! and Aragog! Poor spidey.
And I want some of that potion. Luck be a lady.
I also need to filk "Luck be a Lady" -- except starring Eris/Discordia. In non-Potter news.
