Man hong kong, you just posted a pic of japans greatest boy band! I love them, they sing the song YATTA, just look it up on a kazaa media share program. I dont think they're actually gay, they do comedy skits in japan similiar to Saturday night live.

 

My friend did something similar on his Bronco(?). He turned the rear washer nozzle to point upwards, so at highway speeds he'd have a massive roostertail, hitting every car within like 30 feet of him! Then he went a step further...he added another tank and an electric switch to choose between the two. He filled up the 2nd tank with some junk that leaves a very visable stain on paint.....

 

How about a potato launcher? imagine cars stoping to remove all the mashed potatoes from their windshields .
