Working as a guide in the North Maine Woods one summer, I had the pleasure of canoeing with a crew of Scouts from the British Isles for two weeks. This was one of their favorite songs. A couple variants are close to same words but:

"...Mrs. John Brewster,
Who sat, and sat, and sat like a rooster,
'Til Neptune came up with his trident and goosed her...

"The last one in was old Mrs. Draper,
Who got so darn hungry she had to eat paper,
And all that came out was an obnoxious vapor,
And EVERYONE knew she was there.
