I was driving home from work, cruising in the slow lane of the freeway, when this big, brand new silver supersized pickup truck does a hillbilly fly-by and then drops back, and pulls up along side me. His truck sounds pretty cool, BRRRR, BRRRRRRRR, but thick black smoke belches out of what looked to be at least a 5" exhaust tip with each blip of the throttle. There's this queer guy leaning out the backseat supercab window, waving me along, trying desperately to get me to run. I ignored him for about a mile until I just said poop it, and dropped into 4th and mashed it.
Suddenly, more black smoke than the little engine that could had ever produced blasted out the back of him, blotting out the sun which was in my rearview mirror within about three seconds. I had plenty of space and speed to pull in front of him and watch as the black cloud behind the truck seemed to eclipse the truck making the mess, which got smaller and smaller, and finally the smoke stopped belching as the truck gave up with a pathetic anti-climax about 30 cars behind me.
I slowed down, but he slowed down-er, and never came within ten car-lengths. He was teh loser and now his truckload of buddies knew it, too. If only I could have heard the convo they had at that point.
