Call My Bluff (Sat 16th Apr 1994 BBC Two) 

BBC Two's 30th birthday celebration one-off edition of Call My Bluff:
A new edition of the classic panel game. Joining team captains Frank Muir and Joanna Lumley are Peter Cook, Jonathan Pryce, John Gordon Sinclair and Celia Imrie.
Chaired by Robert Robinson.
Now, you might think that as soon as Peter Cook mentions Sonja Henie that his definition must be a Bluff (or "bleurf" as the Struebs would say); well, maybe it is, but then again maybe it isn't.
