Throw It In / Radio

• In The Hitchhiker's Guide to the Galaxy (1978), the comically anguished scream presented as "this recording of a man being put into the Vortex" is actually a recording of Simon Jones reacting to a piano lid smashing his fingers.
  • In an earlier episode, the Golgafrincham B Ark has "tired TV producers" aboard. This was supposed to be "Tri-D TV producers", but the scripts were misprinted and the production team thought the new line was just as good as the original.
• During the episode "TV Documentary" of The Navy Lark there's been a Running Gag about Leading Seaman Riddle being called to the Bridge but he never turns up. During the climax the messenger says that he realises where Riddle has been all this time.
  "I'm Reading Seama-" [audience explodes with laughter and the actor stumbers for a short while] "I'm Leading Seaman Riddle!" [audience cheers]
• In "Bleak Expectations" Anthony Head, in the role of Gently Benevolent, is pretending to be an American named Harlan J Trashcan and suing Pip Bin over the royalties for the invention of the bin. Part way through the court scene he had trouble getting back into his (very, very obviously fake) American accent after two other characters had been speaking. In the process of attempting to get into the accent he says "sorry, can't get the accent". This was left in, along with the slightly odd sounds he made trying to get the accent back, and is not remotely out of place (nor is it at all surprising that Pip still does not immediately realise what's going on).
