Duncan: Logan? Logan, are you awake?
Logan: >grumble, grumble< I am now.
Duncan: I'm worried!
Logan: >Sigh< What else is new?
Logan: Okay, tell me all about it.
Duncan: It's Daddy John. He's going to visit Loch Ness while he's in Scotland.
Logan: Yeah, so?
Duncan: What if he runs into those aliens?
Logan: What aliens?
Duncan: You know, the shape shifting aliens from the TV documentary we watched.
They live under Loch Ness and control the monster. They can change into people.
What if they capture Daddy John and assume his identity?!?
Logan: What?!? Wait a minute...you goof; that wasn't a documentary.
That was an episode of Doctor Who! There are no aliens and no monster!
Duncan: But we don't know that for sure. What if it's true?
Logan: I'll tell you what; as soon as Daddy John gets home,
we'll make him open his mouth real wide.
If a tentacle shoots out, then we'll know he's an alien doppelganger.
