Hi Led Ballon,
try to confuse them on the continent, which is easy!
They will never find out, if you express everything in imperial units... - and make it difficult: inch, foot, yard, link, ell, step,...
At least in Munich, all you need to know, is a "Maß" (or "Mass" to omit the german "sharp s") (of beer), which is roughly two pints or a quart - you'll have their sympathy...
