A
fictional institution in the bizarre
parallel universe inhabited by the Goons of
The Goon Show fame. Situated in
London, the
Ministry deals with
monkeys on the knee, and will provide information on the same should you send them two rust-proof
shillings.
Presumably, the research boffins at the Ministry were the ones who determined that monkeys on the knee can be cured by saying "Thing".
Basically an excuse for another bit of nonsensical malarky to spice up the BBC listening schedule.
