I recall this joke from around 1989.
A German man and an Australian man walk into the bar at the Hotel Moscow in St. Petersburg and notice only two chairs available, at a table where a Russian man is sitting. They ask if they can join the Russian. He agrees and all politely acknowledge each other. It is important to note, that all three men are sober. The German and Russian strike up a conversation and begin speaking quickly and passionately about life; yet, the Australian does not join in the conversation. He remains silent. Just listening and watching the two men speaking. Finally, the Australian man cannot take it any longer and asks the men, “What language are you speaking?”
The German and Russian look at each other a bit confused and back to the Australian.
Then the German replies hesitantly, “English.”
The Australian stares at his two table mates before responding, “I don’t understand you.”
