What I heard from an expat Englishman back in theearly 50's was:

Mary, she was pretty; Mary she was witty,
She went into the city
Just to serve on a committee.
A man on the committee, just to prove that he was witty
Smote Mary on the titty with a hard boiled egg.
    Rule, Britannia, Britannia rules the waves,
    Britons never never shall be
    Smitten on the titty with a hard boiled egg.
