Okay! I see another door, and it (thankfully) looks relatively harmless! Let's go!
You follow me through the blue door and after the starting-to-get-old flash, we find that we are in a city! A big, smoggy city! Boy oh boy, do you smell that restaurant? We should- where are you going? That police box? What? Do you have to make a phone call? Don't smirk at me! That's what I was doing to you! Don't go in there, you never know what might happen in these universes ...
What did I say! It's already occupied. Doctor who? How do you know that guy is a Doctor? And how should I know who?!! Why would I care!! ... What? He is not good looking! ... Okay, so he is, but let's not bother hi- okay, now he's looking at us funny, I say it's time to leave! Come on! We are not staying to have some guy stare at us! Don't make me drag you ... thanks, I wasn't really going to drag you.
What the what?! Why is he following us? Okay, that is officially creepy, let's run! No don't stop! ... Harmless! That's it, you are geeking out about this weirdo! I drag you back through our door closing it firmly. Now, pick a ... less ... weird one.
