"A boy took a girl in a little canoe
With the moon shining all around
And as they paddled that little canoe
You couldn't even hear a sound!
So they talked and they talked 'til the moon grew dim
And the boy said Kiss me or get out and swim
So what'chu gonna do in a little canoe
With the girl paddling all-a
The boy swimming all-a
The moon shining all around?
Hey!"

There're hand motions, too. The way I learned it was actually with the girl getting out and swimming, but I like this version better.
