Here are some tips from the Ugly American Travel Journal (June '04):
If you are planning a trip around the world this year, it is important to know a little about the language for each country you will be visiting. Now, while it is not possible for most if us to learn enough of each language to carry on a decent conversation, there are a few words or phrases that are critical in every country...so at a minimum, make sure you learn the following:
1) Hotel
2) Beer
3) Bathroom
4) How much?
5) Sorry, officer
6) ...and, as many expletives as possible.
