I am a little bit puzzled by this cartoon: http://ozyandmillie.org/d/20070802.html
Why should that expression be a puzzle? I think the origin is perfectly obvious.
In the UK we have a tradition called Punch And Judy. It’s a puppet show starring a grotesque grinning anti-hero called Punch. Punch grins. He looks very pleased with himself. Every British child will know it.
Are these shows relatively unknown in America? Would an American child really be puzzled by the expression “as pleased as punch”
American dopers, have you ever seen a Punch And Judy show?
