"Pigs in blankets is small (cocktail) sausages wrapped in bacon."

I take it that those small cocktail sausages are the ones known to my teenaged daughters as "little boys"?

McGrath, I don't think cops in Oz have been called traps since colonial times. But they have been called pigs for quite a while. When I was protesting the Springboks tour in Melbourne (1971) a copper rather aggressively suggested I regarded "all cops as pigs". Being a volunteer in search and rescue I wasn't but I rather took the wind out of his sails with the reply "No! Cops have souls!"

And, when the police acquired a Dauphin helicopter (powered by twin gas turbines, I believe) its distinctive sound earned it the name "the pork chopper" from the kids at the sschool I taught.
