The way my mother sang it:

There was a bold fisherman started forth from Barnegat
To catch the mild pogy (porgy?) and the brave mackerel
But ere he rove o'er Pimlico, the stormy winds they did begin to blow
[alt: But ere he rove o'er Pimlico, his little boat did wibble-wobble so]
His little boat did wibble-wobble so, plumb overboard fell he.

Twinky-doodle-um, twinky-doodle um, was the very interesting song he sung
Twinky-doodle-um, twinky-doodle um, the bold fisher-mun.
