Thanks for answering my last question. Here is another vague movie memory I have. A man and a woman are pulling this huge boat, like a big fishing trawler or something, behind this jalopy of an old truck. The boat just dwarfs the truck. The truck stalls or something and they can't get it going. They just happen to be next to a lagoon or something so they push the boat, trailer and all, into the water and the woman exclaims 'It floats!' to which the guy responds 'Of course! What'd you think?' or something like that. And then they just stand there watching it float away. I remember thinking "What about the trailer? Are they just going to leave it?" Sound familier anybody?
