"Hey! The Walk of Fame! I'm in Hollywood! 21st century..." the Doctor realized as he saw the stars in the pavement beneath his feet after stepping out of the TARDIS. "Hm… Ah yes! Charlie Chaplin! I must've forgot to—" he paused, cut short when he noticed the alarming amount of strange looks he was receiving in his direction. Puzzled, the Doctor looked around and back behind him towards the TARDIS. He saw a familiar shade of blue, but a rather unfamiliar shape…"She's a bloody port-a-loo!"
Completely horrified, the Doctor frantically ran back into the TARDIS and set the coordinates to 1960's London. "There we are then!" he said in relief after landing. He started towards the door to check on the current camouflage of his ship, but then he stopped dead in his tracks when he spotted an unnaturally orange, blonde humanoid female standing before him.
"Oh. My. God. This is, like, the weirdest port-a-potty I have ever been in!"
"What?"
"Huh?"
"What?!"
"You talk weird. Are you like, foreign or something?"
"WHAT?!"
