I suspect many people under the age of 25 probably don't know of the Batman television series that ran from 1966 - 1968. Of course, it lived in syndication for many years after and when I was a kid in the early 70's it was must see TV.
Most remember the iconic Batmobile, with good reason, from that time but if I recall, also there was the Batcycle, the Batcopter and the Batboat (above). There may have been one or two more that I've forgotten but in any case, I just remember that Batboat (or is it Bat Boat?) had me and my friends rolling whenever it appeared. It was cheesy enough to laugh at but cool enough that I know everyone wished they had one.
