We were drinking a beer with one of our landlords the other night, Bernd. We tapped our Weihenstephan bottles together and loudly pronounced "Prost!!" Bernd told us to be careful with that declaration. In Germany, the tradition goes that when saying "Prost" you must look your fellow beer drinkers directly in the eye. Anything else, a glance away or no attempt at eye contact at all will result in 10 years of bad sex. See, beer drinking can be serious business.
