Were at this small bar that I frequent and and aquaintence of mine had a few to drink and decided to put on a show in the parking lot. He has a 7.3 Powerstroke. He starts revving it up. We start egging him on. He put's out this huge smoke cloud and it all goes into the the open door of the bar. People come running out of the bar from all the smoke and smell, the band that was just inside the door thought their equiptment blew up. Diesel truck clears bar, who would have thunk it.
