First they all need to get in the cab, then send the lightest person out to collect rocks or….
You would imagine they might be a bit of rope lying around the bus, they could lasso the gold and haul it to the front.
The obvious thing that annoys me though is the fact that instead of one person going to get the gold, they all try to shuffle down the bus, now if the rest of em had got far forward in the cab then one person could grab the gold and start throwing it up the bus.
Still its better than the crap american remake.
