His boss called him "FUCKING ASSHOLE", so he took his Super-Mouse fizzy drink. As his body assimilated the wondrous drink he started hearing the boom boom in his head. At the rythm of the boom- boom he took the gun his mind just created with the power of his own imagination and replied "SHUT THE FUCK UP"....then he kicked his boss´ ass, took the fucking money and spent it in the only thing a giant mouse would spend money: a massive sponge cake.
BOOM BOOM BOOM BOOM BOOM "SHUT THE FUCK UP"!!!!!
