It was sarcasm, yes. The judgmental kind. I'm not always out drinking. It's not weird for you at all to know that the people here have been watching our lives on their televisions? We're not fictional where we're from, but we're not there right now, are we?
Your theory just includes random people being snatched out of their home universes for no reason and coincidentally ending up in this one town where there also happen to be supernatural creatures prowling the streets. How does that make any more sense than the alternative?
