This one may be old on the net (I certainly heard it a number of years ago),
but in case you havent heard it before, here goes a story the Polish tell
about Russians…

A Russian party-official arrives late at night to his hotel (in Russia). He
is not surprised to find that his reservation has been mislaid but he is
more than a little peeved that his status in the party isnt enough to get
him a good room anyway. However, the clerk insists, the only bed they have
left is the fourth bunk in a 4-bed dorm–hell have to make do with that.
The Russian grumbles but eventually he picks up his suitcase and heads for
the dorm. On his way, he meets a chamber-maid and thinking he might as well
try to make friends with his room-mates, he asks her to bring them four cups
of tea.

As he enters the dorm, he finds that the other three guests are Polish, they
are having a fairly wild party and theyre very drunk. They also ignore him
totally from the moment he enters. After sitting there for several minutes,
he realizes he cant stand them anymore and decides to pull a joke on them.
He stands up, grasps a floor lamp and speaking into the light-bulb as if it
were a microphone he says:

Comrade Colonel, we would like four cups of tea to our room immediately!
The Poles stare at him in disbelief, which turns to horror as the chamber-maid
knocks on the door and delivers the tea a few minutes later. In about 30
seconds the Poles have all packed their bags and fled the hotel. Our Russian
gets the entire room to himself. He sleeps very soundly.

The next morning, however, as hes checking out and is about to leave, the
desk-clerk calls after him:

By the way, Sir, the Comrade Colonel said to tell you he appreciated your
little joke last night!

As I said, this is a joke the Polish tell about Russians…
