Several years ago a couple of guys went to the airport (Heathrow I think) and got the information desk to read out spoof names that sounded Arabic but became sentences. It was on Utube I think and as far as I know, it wasn`t a spoof. I remember my friend sitting infront of his computer listening to it and laughing his head off. It`s probably still on there somewhere.
I really did fall for being told to tannoy Mike Hunt in my first couple of weeks in an HR dept. I was so innocent I didn't even realise until weeks afterwards when someone joked about it.
