You go back to your own time, only to find the world to be now populated by generations upon generations of your accidental descendants. You are soon worshipped and brought to a divine level due to your 7 billion children/over-zealous followers, who believe you to be their creator. Almost as quick as your rise to God-hood, your ego grows exponentially and bursts from your skeleton, which bursts from your body, which kills Billy Tilly you.
I wish Broby's dick would survive this ego explosion tragedy.
