The Creature from the Pit

This is the side panel of a sort of inflatable tent thing in Bristo Square that a rep from Deloitte and Touche was standing in trying to entice students to join the satanic world of accountancy.

But what it reminded me of was one of my first Dr Who memories from childhood- a 1979 story called "The Creature in the Pit" which had Tom Baker meeting a big green blobby alien (which wasn't an accountant).
