When we see someone in such a rush to do something or in such a hurry to say something like good/bad news and they act all weird moving or talking fast and loud we say
'Have you brought a head?!'
'Look at him. Looks like he's brought a head.'
I think it refers to the wars in past where after defeating the enemy's army, they would cut off the enemy's leader's head and send it to the king by a soldier. The soldier rode his horse fast to the palace not wasting a second. Entering the palace, he loudly shouted the news while he was out of breath or talking fast.
What would be the best equivalent for this in English? Any idioms or idiomatic expressions?
