That's perfectly normal. I'm sorry you feel ill.

The car alarm did add a nice realistic facture to iti want my 32 seconds back.
Because two guys couldn't possibly have enough strength to pull a 175 pound dude back far enough to propel him that far. Also notice the bungee isn't really stretched that far. It would have to be super tight.
The car alarm was a nice touch though.
