CNN lays out all possible scenarios for faithless electors, and possible Vice President elect Pence being POTUS?! Never heard this before

What happens in the extremely unlikely scenario the Electoral College goes rogue?

Donald Trump is busy building his Cabinet and planning his agenda, but he isn't really, officially going to be President quite yet. One of the peculiarities of American democracy is that it's actually a group of 538 "electors" -- members of the Electoral College -- in this nation of 318 million who actually pick the president.

They'll do it, meeting in their respective states, on December 19th. The outcome is a foregone conclusion, but there is room, however small, for a surprise: an uprising, as called for by some Democrats and even some Republicans, of "faithless electors."
None of the electors are constitutionally bound to follow the will of the people they represent, and so in this bizarre election (and post-election) season, an arcane system that was established at the Constitutional Convention of 1787 could -- and this is very unlikely, but could legally -- go rogue and potentially deny Trump the presidency.

....So if the deadlock holds and the House can't vote on a winner -- even more unlikely considering 33 state delegations are controlled by the GOP! -- then the new Vice President, as selected in the Senate (with a potential deciding vote from a familiar face), would become the acting President. Here are a few more unlikely steps that could turn the election results on their head:
