I would force each member of congress to best each other in a series of physical feats of my own design.

>Go to humanworld
>Steal a digital video camera, tons of memory and spare batteries
>Go back to horseworld
>Wait for night
>Use magic to entirely alter my appearance, so no one can recognize me
>Murder Princess Celestia in sleep
>Go into hiding, go back to my normal appearance
>Meanwhile, a civil war breaks out in Equestria
>Start recording everything possible
>Do it until the war ends or Equestria is entirely consumed in flames
>Go back to humanworld again
>Edit all the gathered footage into an actual live-action movie
>Start selling it to Brones
>Soon all humans recognize it as the best movie ever made in that shithole
>Earn billions
>Become the richest human alive
>Die of cancer

Wait, I think I should re-think it a little…
