The version I learned ack in the 1930s was like this

How do you do Andy Gump how do you do
How do you do Andy Gump How are you
How is Chester how is Min how's the whiskers on your chin
Growing out or growing in
How do you do Andy Gump How do you do

Of course then you could add your own versions and someone else add their version and the song would last for at leasy 30 minutes and each verse would be different
