In a scene near the end there is an early rock and roll band. I thought something was fishy when the P the guy was playing sounded a bit... bright. And then it showed the bass.
It was a Stingray. In ~1955.
I went into dry heaves.
You can insult my mother all you want, but when you start making bass-related anachronisms, things get personal.
I'm calling my lawyer right now to discuss my options.
