Random Scientist Man: Ever been potholing?
The Doctor: No, not for a very long time.
HE IS WEARING A BLACK VELVET CAPE. IT HAS A DELICATE RED-SATIN LINING. HE HAS RUFFLES AND A CRAVAT. DOES HE LOOK LIKE HE REGULARLY GOES POTHOLING?! WHAT THE ACTUAL FUCK?!
Ah, but the Third Doctor was a man of action, even while wearing those clothes. It’s not an entirely unreasonable question. ;-) (However, in Silurians, he actually changed into more-appropriate gear to go caving.)
I was particularly amused by his outfit change. XD
