Anyone remember an old animated short (Warner Brothers) from the 1940s or 50s (that I would have seen in the early 1970s) that featured a cruise ship to Antarctica and reference to midnight sun and days and nights that last six months?
I don’t remember a cruise ship, but there was a Bugs Bunny cartoon where he accidentally ended up at one of the poles while on vacation and became friends with a little penguin. He was thrilled when he learned the nights were six months long, because it meant he didn’t have to go back to work for ages.
That’s got to be it - I remember the “ice-breaker” and the calendar-clock, very well. I’m probably combining this one with other cartoons I saw 45 years ago, but finding this satisfies my nostalgia-wish.
