Here's how I would have ended the last limerick:

On a cargo ship headed for Duluth,
I went in search of the simple truth.
I knew the answer would be found,
Even if we had to turn around.
Now where is that fountain of youth?

And to continue the lastest:

There was an old 'wickie' named Ned.
Who often baked a great loaf of bread,
Added three bags of nuts,
