I used to go to the folk club at the Suffolk Punch in Ipswich in the 60s, at the time when Bob Davenport was a regular, and an old chap, who I assume was Percy Webb, often used to sing it; One of his verses was:

If you've got a jawing wife, take her in a boat,
Row her out, throw her in, see if she can float,
If she goes down and up three times, then you begin to think,
Take your oars, row away, and leave the old bugger to sink!
