Welcome to London Heathrow where it is Bikini wearing 20C".
If you heard this on a Virgin Blue flight then I'd suggest that something has gone seriously wrong...
Was the FA wearing a balaclava and brandishing a pistol and a dodgy middle eastern accent?....Did they use the word "infidel"?
Or...Was it a case of a pilot slipping a pocket knife past security and then saying mid flight... "Bugger it, I feel like going to London".
