Hang on a sec… The TARDIS is big…

Just watched “The Three Doctors” from 1973. A UNIT soldier enters the TARDIS for the first time, looks around… mouth agape… and doesn’t say anything.

The Doctor says, “Well, Sergeant? Aren’t you going to say that it’s bigger on the inside than on the outside? Everybody else does. ”

And Benton says, “Well, it’s pretty obvious, isn’t it?”

Beautiful.
