Kitten Kong - S2-E7
Other mistake: When Twinkle (the kitten) is up the tree, Tim starts to throw up sticks, and, as a result, a big log falls on him. The 'log' is plastic, and is a completely different colour from the rest of the tree.

Genres: Comedy
The Goodies and the Beanstalk - S4-E4
Visible crew/equipment: When the bath goes off the cliffs, you can see the string lifting it, so it is obviously on a crane.

Bill: Christmases come, Christmases go. They're all the ruddy same - no one ever remembers them.
The Bunfight at the OK Tea Rooms - S5-E12
Trivia: Graeme Garden made sure his back was padded for the death scene at the end where he planned to throw himself backwards onto the ground. When the time came, he twisted around and landed flat on his unpadded front, to the eternal amusement of his co-stars.
