Nah. It takes an incredible amount of force to block an exhaust pipe. The mythbusters tried the banana/golf ball in the exhaust trick, and it just shoots the blockage out like a cannon.

expanding epoxy glue isn't the same as wedged-in fruit.

so we cant be sure unless we test it, a lot.

The trick would be to somehow get the film of the guy trapped in his burning truck onto his own YouTube channel without getting caught...

I suppose I could buy a cheap digital camera with cash at a swap meet or somewhere without many cameras, then take a bus (cash ticket) into wherever this guy's town is. He'd probably give up his YouTube login pretty easily once the fire started. Maybe I could use his own computer to upload the video? But I'd have to stay at his house way too long. Public WiFi would be my best option. I'd have to find a place with WiFi and no cameras though, might not be possible. And I'd have to buy a burner computer to go with my burner camera. Hmmm.
