Yep - That's the area I thought you meant - good description.

I must apologise, I thought I knew what you meant by the Catchphrase noise and based my answer on that but Mrs _f has just pointed out I was thinking of the Family Fortunes UHHH UHHHH (big raspberry noise when they get the X) instead which is why I suggested the PTU. Clearly this was not what you meant - my mistake - sorry.


I think the posters suggesting the oven have the answer.
