Jesse was sitting on the dirt bike that was sitting on the bow of the Minnow as Skipper looked at him in the rear view mirror while trying to keep his eyes on the road at the same time. Now Jesse had something in both of his hands as he straddled the dirt bike trying to keep from falling.  He noticed Skipper's eyes looking in the rear view mirror so he revealed the first one. It was a moonshine jug. Jesse turned it upside down to show Skipper there was nothing in it. Right away Skipper realized Jesse had used the Professor's coconut moonshine to put in the gas tank of the dirt bike.  Jesse tossed the jug down. What he wouid reveal in his other hand would change the complexion of the entire race.....at least for awhile.....

Hobie still seems to have a very slight lead over most of the crowd , since he just passed Garrett! . Hobie is wondering ( as is most of the crowd ) What the Hazzard does Garrett have under his hood? How is he making it move so fast? He's trying not to show his surprise as Garrett continues to fight him for the lead!

I see things happen there too with shows like in Gilligan's Island, users flip the film around so in the scene "a three hour tour a three hour tour" the Minnow sails left to right instead of the original right to left, and some videos have the sound highly slowed messed up in them too.
