My vote goes towards the disco beam!

Primary fire blasts beams of techno hip-hop or trance music forcing your target to SHAKE SHAKE SHAKE THAT BODY SHAKE SHAKE SHAKE THAT BODY! The longer your target is under the beam, the faster and faster they dance until they explode!

Secondary fire paints a target for a disco ball to drop down and the map starts lighting up with flashing colors so that every body has to dance now, do, do, dodo, do, do, doo everybody dance now, do, do, dodo, do doo.

Fire modes: DubbStep, Lady Gaga, Micheal Jackson

if my calculations are correct the stupidest gun would be a gun that wasnt a gun at all
infact it would be a gun that actually helped the person you were shooting at

so if you made a gun that actually fired guns towards the person you were shooting at then that would be the stupidest gun of all am i right

it would be called the gun that shoots guns towardds the person you are shooting at gun that the person would pick up the gun you shot the person with gun that they would shoot towards you gun that shoots guns towards you that you would pick up and shoot the person you shot the gun that shoots guns towards people gun that you picked up and shot the person again with the gun that shoots guns that the person would pick up and shoot you with the gun that shoots guns at people gun!
