Yes, Prime Minister1986

[discussing a potential appointment]

James Hacker:
Would you recommend him?

Sir Desmond Glazebrook:
No.

James Hacker:
Why not?

Sir Desmond Glazebrook:
City's a funny place, you know, Prime Minister. If you spill the beans you open up a whole can of worms. I mean, how can you let sleeping dogs lie if you let the cat out of the bag? Bring in a new broom and if you're not very careful you find you've thrown the baby out with the bathwater. If you change horses in the middle of the stream, next thing you know you're up the creek without a paddle.

James Hacker:
And then the balloon goes up.

Sir Desmond Glazebrook:
Obviously. They hit you for six. An own goal in fact.
