While it's highly unlikely that Aria, Spencer, Emily, or Hanna could possibly be "A," we're so boggled by the mystery on Pretty Little Liars that we can't help but wonder — could producers be pulling the ultimate trickery on the audience and have one or more of the main girls written in as "A?"

OK, we know it's a crazy (and pretty impossible!) theory, but before you go ripping down all of your "I <3 Pretty Little Liars" posters and deleting the show from your DVR, get into detective-mode for a second.

Hypothetically, we repeat, hypothetically, if one of the main girls was "A," who do you think it would be? Vote in our poll below!

Be sure to tune in for the next episode of Pretty Little Liars on Monday, January 23 at 8 pm ET/PT on ABC Family.
