One scene from The Ordeal, a section of the classic First Doctor story The Daleks, made me chuckle quite a bit due to the old visual effects and general atmosphere. First, after dropping a TARDIS key into a wall panel, the First Doctor told Susan "the power's running away!", in much the same way a parent would say something to their child that's not entirely true, but is ultimately harmless (which makes some level of sense considering she's his granddaughter, but it's still amusing). Then, he bashed in another part of the panel before the power could be seen, running away.
