What the ....?
This is just a random song, not even a really ''mad'' music (mad / madness... or even good)...
An absolutely simple and banal FLASHING multicolors background... really bad... and dangerous too for epileptics...
... and a ''guy'' shoving an rocket launcher and the a** of another ''guy''... really bad taste... not really funny...
So... Nothing impressive, memorable... or really good in this ''flash''...
Try harder next time, please ?
