All this week we've been rolling out hilarious episodes of our self-interview series 'Two on Two' with Tegan and Sara. In yesterday's clip, the twin sisters tackled the awkward question of "Who is prettier?" Today's installment features a discussion on "old school styles of jamming," Leonard Cohen and the writing process of their forthcoming album 'Sainthood.'

Although this clip concludes our 'Two on Two' series, Tegan and Sara's Spinner takeover is far from finished. Next week we'll be featuring their new album in its entirely on our Full CD Listening Party, as well as more exclusive behind-the-scenes Tegan and Sara videos.

Watch today's 'Two on Two' clip after the jump.
