need a simple script that wil allow me to use a animation on command

i need a simple script that will allow me to use a animation on command, eg if i wear a prim with say a dance move in it (just the 1 dance move) and when i say start it will start the anim, and when i say stop it will stop the anim, i already have the anims just need the script, and also needs to work if i give the prim with the script and anim in to other people, thanx in advance.....
