Whenever I want to demonstrate my surround sound I use the scene of Marty returning to 1985. When he returns, there's a police helicopter circling, and the sound of the helicopter makes a full 360 in the room.
Natural gas or propane tank that was installed in the trunk behind the rear passenger seats. Happens on occasion in other countries. Practically unheard of in the U.S. because of DOT tank standards.
This is straying away from dark humour and into politics.
I have my opinion and you have yours
I don't think I want to go any further into that territory
