You wait ages for a winner and then, what do you know, two come along at once. We have a winner - two in fact! In joint first place we have
mylodon and
eglantine_br.
mylodon: The Hornblower Advent Calendar - open a window and Wellard "comes out".
eglantine_br: Ceiling Wellard is watching you...
Congratulations! You're daft the pair of you...
