Bol zup we had a classic pan call a few months ago from a Scandinavian operator. Phraseology was exactly as the book required.
I have personally had 3 in the last 10 years and they were all very clearly called. Then again I've had lots of US registered aircraft who seem to have a lengthy conversation about something not working and have to be asked several times if they are declaring an emergency. The most urgent reply is usually along the lines of ..... yeh I suppose so.
