Turbo Dismount is a game where the little guy falls out of the car and then the car runs him over. Turbo Dismount is where the little guy pedals his tricycle off of a cliff and down five stories onto landmines which launch him up into the air. Turbo Dismount is where the little guy does a loop-de-loop on a section of road and drives straight into a patch of landmines at top speed, making him and his car explode rather spectacularly. Turbo Dismount is where a guy gets into a drag race and finishes it by plowing his car into a wall.
I could tell you about a hundred of these stories, but it's basically a guy, a car, and a set of circumstances in which you have to figure out how to inflict maximum pain on the guy, and the punchline involves grevious bodily harm.
It's a joke you can re-experience and re-tool over and over, but the punchline itself starts to get stale around four hours after you've played out all the variations of "What happens when an (adjective) (character) in a (type of car) drives into a (insert hazard here)?". It's a bit like Mad Libs, but with physics and objects.
I don't see myself playing this again anytime soon, but the time I did spend with it was hilarious, and there's a level based off of the Springfield Gorge scene from an early Simpsons episode called "Bart The Daredevil". So there's your recommendation.
