I'm not sure if this works in all servers or servers that just don't allow melee or w/e but here is what you do
First go into your force powers and turn your saber attack to 0, this will make you have melee instead but only beable to punch and you must die to see the changes. Then find out what your use force key is, by default I think it's 'f' but to find out or to change it go to controls and it's under forcepowers1 as use force power.
Now what you do is just start walking for instance and hold down the use force power. Then stop walking but keep it held down, you will notice your shoulders keep moving and it looks like you are doing a dance. What it does is whatever move you are making when you start holding it down you will keep, for instance if you are doing the little crouched walk and hold it down when you stop walking it will look like you have ape arms, it looks quite hillarious. This might only work on servers that don't allow lightning and grip ect
Here is a screen shot of me walking around and looking like an airplane sort of lol I held it after a front flip and my arms were straight out...This showed up at first but I don't know if it will now...
