Disarm your weapon and set it on the [F1] to [F10] hotkeys. Then, press [Dance] and the [F1] to [F10] shortcut with the weapon together. You will get to dance with the weapon.
Jump in any direction then hold [Shift] and click in another direction. Your character will face the way you clicked, but still move in the direction of the jump. This has no real use except for entertainment.
There are actually two ways to log out from the game. Press [Esc] and a box will appear, asking you if you want to exit. The other way is to click the "Setup" option, then click "Exit". The same box will appear.
Although there is no "log out" feature, there are many glitches in the game that will allow you to log out rather than closing the entire game and restarting it. Once such way for log out (or disconnect) is to jump as far as you can back and forth. Once in the air during a jump, quickly move the pointer back to where your character jumped from and click while you are still in the air. Keep doing that back and forth movement and you will eventually disconnect and be sent back to the log in screen. Another glitch has the same outcome, but a different way of applying it. First, go the "actions" and hotkey at least four of them (for example, [F5] for Wave, [F6] for Lie, [F7] for Cool, and [F8] for Sit). Start pressing all four of these hotkeys at the same time. Your character looks as if he or she is having a seizure, and you will get disconnected. These glitches are useful if you want to log out and relog in with another character.
