Remember that hilarious little video from a car show featuring the "Limited Edition Mustang GT-R" that purportedly has a turbo-rotary engine with pistons and headers? (For non-car people, a rotary engine can be turbocharged, but it certainly cannot have pistons, and of course can't have headers because that's where the turbo goes. Overall, the ridiculous combination of modifications stated just goes to show how immensely little the owner knew about cars other than the knowledge he picked up watching The Fast and the Furious.
Well that's not it; below is a whole 'nother can of worms of stupid and ridiculous car comments made by people, although there is no video.
