<NZ tangent>
When a Brit here offers to 'knock you up', it means 'knock on your door and get you started with the day'. In NZ, they're offering to impregnate you.
The other term that causes much hilarity here (NZ) is when Ozzies refer to their 'thongs'. I once overheard a group of post-grads organising a trip to the beach. The visiting summer student from Oz (female), trying to establish what the standard dress code was, asked "Do I wear my thongs?" To which, the guy organising the outing went kinda red and stammered "uh... I guess? If you want?"
disambiguation: thong (Aus) = jandal (NZ) = flip-flops (US)
thong (NZ) = g-string underwear
Oh, and one more! "Randy" is not a name you should be using here, no matter how much you hate "Randalf"
