Happiness isn't happiness without a violin-playing goat

If you know the answer to two questions, then a) you are a true film buff and b) you can say that you know me better even than I know myself.

Make it three questions:

a) Which film does the title of this post come from. Film, not painting.
b) Why have I stayed up to be so moved by it?
c) Who am I paraphrasing in the opening line of this post, and who was he pretending to be?

OK, five questions.

I'm bored with this weather now, I. Need. To. Go. CYCLING.
