I spent the finest $4.99 of my life Sunday. I bought the Batman Movie (Adam West) on DVD. I don't think this requires any further explanation.
Though I should also note that I spent a rather fine $10 or something today as well, on Little Miss Sunshine. This is a must-see. It was so much fun and uplifting without being condescending or sappy. I loved it and laughed and had the most fun I've had at the movies in a little while. Go enjoy it- now! (shaking fist)
