I know that under those conditions the accepted practice is to yell "Emergency! Scram the reactor!", but I feel "Alah-u Akbar!" is shorter and more punchy.
Angels? What are those then? I mean, I'm all for knocking off and going down the pub, but voices in the sky singing about how we're all to go down to this scruffy travellers' inn, sounds like you've had a few already. More likely some local band advertising their gig in the back garden.
