A Russian arrives at a friends house with a bottle of vodka. The friend silently leads him into the dining room where they both sit at the table with the bottle. Not a word is spoken.

The friend goes off and returns with two vodka glasses. The Russian fills the two glasses with the vodka, and they begin to drink. Not a word is spoken.

After much silence and a half-empty bottle, the Russian ventures a comment, “Good vodka, agree?”

At this, the friend slams down his glass and replies, “Did you come here to talk or to drink?”
