Headscratchers: Doctor Who S32 E4 "The Doctor's Wife"
WARNING! THERE MAY BE UNMARKED SPOILERS!
The Tardis chides the doctor because he always pushes her door instead of pulling, like the "instructions" on the police box say. However, those instructions are on the small telephone which you pull open to access, not the actual door you walk through.
Well, she has gone pretty loopy from all that travelling. And being a Sentient Ship, she probably has some interesting habits.
