A few months ago, we rented a collection of old Looney Tunes cartoons from Netflix, and in a short I hadn't seen in years (
Tweety's S.O.S. (1951) set on a cruise ship) there's bit where Tweety, being chased by Sylvester, turns around and holds up a painting of a ship at sea and rocks it back and forth, causing Sylvester to get seasick and dash for the rail. The music played while the painting is rocking is none other than the tempest music from Wagner's
The Flying Dutchman, which fact escaped me years ago and almost made fall out of my chair this time.
