I just asked for a band-aid. Rather than a plaster, which is what we call them over here. (Don't worry, my thumb is fine. I just knocked the scab off whilst washing up.)
I have been known to say things like "Shall I put this in the trunk [boot]?" or "Can I borrow ten bucks? I mean, ten pounds?", and I have been mocked for saying "Stick it in the trash can" rather than "Put it in the bin."
That being said, I don't think I'll ever say "Math." ;-)
