When Austin powers is taking pictures of himself when he was frozen, he says: "You're a popsicle baby!" The British don't say "Popsicle", we call them "Ice lollies"

Secondly, when Felicity asks Austin if it was worth going to the nineties and missing the seventies and the eighties, Austin says: "The seventies and the eighties? There was a flock of seagulls and a gas shortage. That's about it!" Again, we don't say "gas" we call it "petrol!" Just shows how much research they put into that film.
