Although I could relate several amusing stories, I think I'll just sum up some of the more poignant differences I observed in a set of rules I've established as a sort of 'American's guide to the UK'

• Left is Right.
• Up is Down.
• Zero is One.
• Public is Private.

These apply to driving, lightswitches, building floors, and schools respectively. Once one wraps one's head around these paradoxes, one is well on one's way to understanding the wonders of British living. In all seriousness, though, I was most taken with how similar things are in the US and the UK - we share very similar cultures. [and Fermi levels - Ed]
