If I ever gave into my occasional desire to become famous over the Internet, I think I've discovered just how I would do it:
Drunk History.
In which a person gets very, very tipsy and discusses a historical event, which is later acted out by various celebrities. Doing this would combine my two great skills, which are telling humans things and making poor decisions under the influence.
And there's so many things that I could discuss. (Not the Spanish conquest of the native Mexican population, though, as that just ends with me screaming, sometimes throwing things,
crying and occasionally becoming a snake. It would turn into something ugly) The Mexican-American War would be a possibility, or the French invasion. Some of the stories about Pancho Villa or Benito Juarez would also work. If it has to be an event from American history, the Battle of the Alamo would do nicely; Americans have some tragically mistaken notions when it comes to the history of Texas.
I wouldn't want to do the interview on someone's couch, however. I'd want to be in a leather chair, holding a smoking pipe, with a fire blazing behind me. If I'm going to be intoxicated in public, I'll at least look very stylish while doing it. I think that's fair.
