Here's a joke I found. Pretty funny, [you need to understand a bit of ASCII Art to get it]:

Russian Soldiers Obey Orders

A line of Russian soldiers stands in front of a huge rectangular hole in the ground.
Their Sergant commands:

- "Private Ivanov!"

- "Yes, sir."

- "Stand like this:"

                          O
                       _|______
                      | |
                      | |
                      | |
                       | |
                       | |
                       | |
                       | |

-"Jump!!"

The soldier jumps into the hole. The sergant commands again:

- "Private Pyetrov!!"

- "Yes, sir!"

- "Stand like this:"

                       |  
                       |  O
                       \ -|-|
                          | |
                          | |
                          \-\
                           | |
                           | |
                           | |

-" Yes, sir!"

-" Jump!"

The soldier jumps and falls into the hole. The sergant commands again:

-" Private Sidorov!!"

-" Yes, sir!"

-" Stand like this:"

                             O
                           |-|-|
                           | | |
                           | | |
                           | | |
                            | |
                            | |
                            | |
                            | |

-" Yes, sir!"

At this point a car with the colonel arrives to that place. The olonel, very angry, comes up to the sergant and tells him: "Comrad sergant, how many times do I have to tell you: STOP PLAYING TETRIS WITH THE SOLDIERS!!!!!!!!!"
