Ah, the infamous "AAA" and "AA" - another great example of two nations divided by a common language. Basically:
UK: AA = Automobile Association
US: AA = Alcoholics Anonymous
Hence the look of puzzlement on the faces of my colleagues when I first moved to the US and asked where I needed to go to join the AA!
This goes along with my daughter asking, in class, for a rubber.
UK: rubber = eraser
US: rubber = condom
And for the sweet-toothed members, there's always...
US Milky Way = UK Mars Bar
UK Milky Way = US Musketeer Bar
I'm pretty sure we've covered these things before, but always worth a quick revival now and again (as Billy Graham would say.)
