Me: HEY DOCTOR are we there yet ? are we there yet?
11: NO SHADDAP
~~~~~~~~~~~~~~~~~~~~~~
Me: * climbs TARDIS console*
11: HEY GET DOWN FROM THERE!!!!!!!
Me : COME AND GET ME !!!!
~~~~~~~~~~~~~~~~~~~~~~
Me: * slaps 10 *
10: WHAT WAS THAT FOR!!!!????
Me: SPOILERS!!!
~~~~~~~~~~~~~~~~~~~~~~
A/N I would be a hyper little IJIT
