Columbia University President Lee Bollinger ignited speculation this week when he implied that President Obama would be returning to the school after his years as commander-in-chief are over. "We look forward to welcoming back our most famous alumnus, Barack Obama, in 2017," he said at a school event, according to the college newspaper.

The White House quickly released a statement declaring that no final decisions have been made about his post-presidency plans, and the university published its own statement to clarify that nothing has been decided yet. That said, it's not a far-fetched idea.

Obama graduated from the university in 1983, Columbia made a bid to host the presidential library, and his foundation has already made clear it will have some sort of presence at the school.

So, what would a post-presidency Professor Obama teach at his alma mater? Here are a few possibilities.
