Yeah, I watch occasionally, too. When good 'ole Billy designed his "innovative" underseat exhaust ("I ain't never seen a bike with one of them 'fore," said one dumbstruck biker rally attendee.) I just had to watch with morbid curiosity. The sense of comedic impending doom was too strong to resist.
Hey, Billy, did you think routing super-hot exaust gasses up your a$$ was a good idea? (It's supposed to be the other way around, dummy.) How 'bout some insulation? Oh, yeah, after you lit your butt on fire, you "solved" the problem with a sheet of aluminimun foil. Quite an engineer you are.
You gotta watch. It's priceless.
