The lyrics posted by Jim Dixon leave out verses five and six:
The dark-eyed señoritas are very fond of me, You ought to see us throw ourselves when we get on a spree; We are as saucy as a clipper ship dashing round the Horn; Head and tail up, like a steer rushing through the corn.
I've never changed my fancy shirt, the one I wore away, Until it got so rotten I finally had to say: "Farewell, old standing collar, in all thy pride of starch. I've worn thee from December till the seventeenth day of March."
