As "hokey" as some of the star trek special defects were, I always imagined the special effects budget for the original run of Doctor Who as follows.
<A new production week begins....>
Director: What is our special effect budget this week?
Producer: <reaches into pants pocket> Well, I've got 5 quid.
Actor 1: Ooh, I can add 1 pound to that.
Technician: I've got a sixpence.
etc...
Director: Ok, who's going to the shop to buy the paint, cardboard and tape this week? Oh, and don't forget to haggle.
EDIT: Oh, and I should probably say that I've been an avid Dr Who fan since I discovered it in or near 1976.
