How do you stop a polish tank? Shoot the guy pushing it.
Why is the suicide rate so low in poland? Because you can't jump out a basement window.
What do you do if a Pole throws a grenade at you? pull the pin and throw it back.
And the classic...
How many poles does it take to screw in a light bulb? three. one to hold the bulb and two to move the ladder.
