I liked the hicks one filling drain pipe with gas to burn out a racoon.
Original myth was that they could not get the gas to start so drunk hick climbed in with his lighter to set the racoon on fire, the resulting explosion sends bubba flyin 200 feet through the air landing safely but a little worse for wear.
summary myth busted using gasoline buttttt
with crash dummy in hand and a healthy 10 lb charge of black powder they were able to make the 200 lb crash dummy fly about 200 feet but the landing probably would still not have helped him any
on the CD one. Geeky mythbuster says "ohhhh! this is horrible"
