But they always end up on top anyhow, somehow...

Vienna, 1907: after numerous attempts, have infiltrated the Academy of Fine Arts and facilitated Adolf Hitler's admission to that institution. Goodbye, Hitler the dictator; hello, Hitler the modestly successful landscape artist! Brought back a few of his paintings as well, any buyers?

All right; that's it. Having just returned from 1907 Vienna where I secured the expulsion of Hitler from the Academy by means of an elaborate prank involving the Prefect, a goat, and a substantial quantity of olive oil, I now turn my attention to our newer brethren, who, despite rules to the contrary, seem to have no intention of reading Bulletin 1147 (nor its Addendum, Alternate Means of Subverting the Hitlerian Destiny, and here I'm looking at you, SneakyPete). Permit me to sum it up and save you the trouble: no Hitler means no Third Reich, no World War II, no rocketry programs, no electronics, no computers, no time travel. Get the picture?
