,,,, was, indeed a Dalek.
Yes, this is 100% true. Back in 1968 'til about '74 me old man appeared on several episodes of Dr WHO 'cept they kept killing him off but he told - nay, convinced me that the Tardis really is that huge inside coz he'd been showed around it by the set director. So There you go!
Furthermore, after recording the shows a little man used to step out of a hatch in the back of the Dalek prop after shuffling it around and wiggling the toilet plunger they used for his nose and off they'd go for pints.
Was never scared of them again after learning that but did wonder if his mate spoke in a funny Dalek voice. Hmm.....
