The infamous and great /bow bug:
Step 1: Spin your character, holding down the A button (by default configuration.). Don't let go of the A button.
Step 2: Press Enter. With your second hand, type /bow.
Step 3: Press Enter. About 1/4 of the way through the /bow animation, release the A button.
It'll take a couple tries to get it to work right. The result is your character spins around constantly -- without you pressing a key. You can move backwards and forwards and strafe and your character will still spin. You'll have to steer with the mouse-look, because if you turn it will cancel the effect.
'Spliot!!
